Docx

docx recipe generates office docx reports based on the uploaded docx template with handlebars tags filled inside using Word application.

  1. Open Word and create docx file using handlebars templating engine.
  2. Upload created docx file as an asset to the jsreport studio
  3. Create template, select docx recipe and link the previously uploaded asset
  4. Attach sample input data or scripts if needed
  5. Run the template, you get back dynamically assembled docx report

Examples

Built-in helpers

docxList

Create a list with single item using Word and call the docxList helper. It will iterate over provided data and create another list item for every entry.

 - {{#docxList people}}{{name}}{{/docxList}}

Example - List

docxTable

Create a table with columns header and single row using Word. Call {{#docxTable}} in the first cell of the data row and end the call {{/docxTable}} at the last cell.

columnA columnB
--- ---
{{#docxTable people}}{{name}} {{email}}{{/docxTable}}

Example - Table

Vertical table

Use helper argument vertical=true for rendering vertical table

name {{#docxTable people vertical=true}}{{name}}
email {{email}}{{/docxTable}}

Dynamic columns

The table can be fully dynamic and even nested. Use rows=[[]] and columns=[] helper arguments to render dynamic columns.

{{docxTable rows=rowsItems columns=columnsItems}}

Merged cells can be generated by passing object to rows=[[]] and columns=[] arguments. For example using this

{
    "rows": [
        [{ rowspan: 2, value: 'R2-1' }, 'R2-2', 'R2-3', { rowspan: 2, value: 'R2-4' }],
        [null, 'R3-2', 'R3-3', null],
        ['R4-1', 'R4-2', 'R4-3', 'R4-4'],
        ['R5-1', { colspan: 2, value: 'R5-2' }, 'R5-4']
    ],
    "columns": ['R1-1', 'R1-2', 'R1-3', 'R1-4']
}

will generate following table:

R1-1 R1-2 R1-3 R1-4
R2-1 R2-2 R2-3 R2-4
R3-2 R3-3
R4-1 R4-2 R4-3 R4-4
R5-1 R5-2 R5-4

It is important to note that the columns and rows array should produce same shape of cells, it means that when you use object with rowspan you have to pass null when a cell needs to be ignored as result of the rowspan layout.

The docxTable helper call provides also @rowIndex and @columnIndex variables, which can be used to generate dynamic content based on conditions using those values.

{{#docxTable rows=rowsItems columns=columnsItems}}
{{@rowIndex}}-{{@columnIndex}}
{{/docxTable}}

docxStyle

Wrap block with {{#docxStyle}}{{/docxStyle}} and pass textColor parameter to dynamicaly specify text color.

{{#docxStyle textColor='0000FF'}}Simple text{{/docxStyle}}

Supported attributes:

  • backgroundColor
  • textColor

Example - Style

docxImage

  1. Prepare image placeholder using word - place any image to the desired position and format it to your needs.
  2. Select image, select Word tab "Insert", click on "Bookmark and create one
  3. Right click image and click "Hyperlink"
  4. Click bookmark and select previously created bookmark
  5. Click ScreenTip still on the "Insert Hyperlink" modal.
  6. Fill the docxImage helper call {{docxImage src=myDataURIForImage}}
  7. Hit ok and close the hyperlink dialog. Now if you hower the image you should see the docxImage helper call
  8. Run the template with myDataURIForImage prop in the input data and you should see the image replaced in the output.

Example - Image

docxImage supports the following configuration properties:

  • src (string) -> specifies the base64 dataURI string representation of the image to load or an url from which to fetch the image
  • usePlaceholderSize (boolean) -> when true the dimensions of the image will be set to the same dimensions than the placeholder image defined on the docx file. Ex: {{docxImage src=src usePlaceholderSize=true}}
  • width (string) -> specifies the width of the image, value can be in px or cm. when only width is set, the height will be automatically generated based on the aspect ratio of the image. Ex: {{docxImage src=src width="150px"}}
  • height (string) -> specifies the height of the image, value can be in px or cm. when only height is set, the width will be automatically generated based on the aspect ratio of the image. Ex: {{docxImage src=src height="100px"}}

docxChild

Allows embedding text from a child docx template (stored as an asset in jsreport or inline) into the caller docx template.

Assuming you have a docx asset "template.docx" stored in jsreport, you can call the child template this way in you main docx template:

{{docxChild "template.docx"}}

this call will then be replaced by the text nodes found in the "template.docx" document.

You can also specific the docx template inline (this allows specifying the docx template in a dynamic way), by passing an object to the helper:

{{docxChild (getDynamicDocxTemplate)}}

you will need to have a helper that returns the following object:

{
    content: "<string content here>",
    encoding: "base64"
}

for example, according to the helper call above, we need to have a getDynamicDocxTemplate helper defined, its implementation can look like this:

const jsreport = require('jsreport-proxy')

async function getDynamicDocxTemplate () {
    // in this case we just get the docx template from the assets,
    // but you can easily get your desired docx template from a fs read or a http request call, etc
    const assetFound = await jsreport.documentStore.collection('assets').findOne({
        name: 'template.docx'
    })

    if (!assetFound) {
        throw new Error('docx asset not found')
    }

    const docxBuf = assetFound.content

    return {
        content: docxBuf.toString('base64'),
        encoding: 'base64'
    }
}

docxHtml

Allows embedding html into docx by converting html tags (<p>, <ul>, <a>, etc) and styles into docx elements (paragraphs, lists, hyperlinks, etc).

The main idea is that you write the helper call {{docxHtml content=...}} in a paragraph of your docx document, this text then will be processed and converted into docx elements based on the tags and styles evaluated in the html.

For example a document with data

{
    "html": "<h1>Introduction</h1><p><a href=\"https://jsreport.net/\">jsreport</a> is a <b>javascript reporting server</b>, which enables innovative and unlimited reporting based on javascript templating engines</p><h1>Features</h1><ul><li>Various output formats can be produced just from the html and javascript (pdf, excel, docx, html, csv)</li><li>Templating engines for powerful dynamic layouts, custom javascript hooks for data fetching, full support for the latest css and javascript</li><li>jsreport includes web based designer, just connect with a modern browser and you're ready to design reports</li><li>scheduling, templates versioning, import export and backup, sub reports, users management</li><li>Use simple REST API, CLI or SDKs to render a report from everywhere</li><ul>"
}

will produce the following document:

docxHtml output

There are two modes (inline, block) in which the docxHtml helper can be used, and you will use one or the other depending on your use case

docxHtml block mode

{{docxHtml content=html}}

this is the default mode, it will look for the first helper call in the paragraph (in case there are other docxHtml calls in same paragraph), and replace the whole paragraph with the content generated with the html, which can include creating even more paragraphs. Use of this mode is recommended when you want to produce chunks of content directly from html, multiple sections with styles, or even produce the content of a whole document directly from html.

docxHtml inline mode

jsreport is a {{docxHtml content=html inline=true}}

In this mode the content of the paragraph that contains the helper call will be preserved, the html will be processed in a way that will only produce text and styles that only affects text. Use of this mode is recommended when you want to replace only specific part of a existing paragraph in the document, or when you want that the html input does not affect the structure of the existing paragraph.

docxHtml supported tags

The following tags are supported, tags that are not part of this list are just considered unsupported and therefore treated as <span> elements:

  • <p>, <div> (to produce paragraphs)
  • <span> and text (to produce text)
  • <b>, <strong> (to produce text with bold style)
  • <i>, <em> (to produce text with italic style)
  • <u>, <ins> (to produce text with underline style)
  • <small>, <sub> (to produce text with subscript style)
  • <sup> (to produce text with superscript style)
  • <s>, <del> (to produce text with strikethrough style)
  • <code> (to produce text with background/highlight style)
  • <pre> (to produce text with Courier font and retaining white space in its content)
  • <h1> to <h6> (to produce paragraphs with heading styles)
  • <ul>, <ol>, <li> (to produce lists)
  • <br /> (to produce line breaks)
  • <a> (to produce hyperlinks)

docxHtml supported styles

For the moment only inline styles are supported (styles applied directly to html tags like <span style="font-size: 30px">text</span>).

The following styles properties are supported:

  • font-size (in px, pt, em, rem, %)
  • font-family
  • color (names and rgb colors, hex, color names, hsl, hsv)
  • background-color (names and rgb colors, hex, color names, hsl, hsv)
  • text-decoration (underline, line-through)
  • text-align (justify, left, right, center)
  • padding (left, right, top, bottom, and shorthand)
  • margin (left, right, top, bottom, and shorthand)
  • break-before:page (to produce page break before content)
  • break-after:page (to produce page break after content)

docxChart

Create a chart inside the desktop word application and use docxChart helper call inside the chart title.

Example - Chart

The helper call in a title can look like this:

A title{{docxChart data=fruits}}

With the following data on the input:

{
    "fruits": {
        "labels": ["Q1", "Q2", "Q3", "Q4"],
        "datasets": [{
            "label": "Apples",
            "data": [100,50,10,70]
        }, {
            "label": "Oranges",
            "data": [20,30,20,40]
        }]
    }
}

The data.labels describes labels on the X axis. The data.datasets includes values for the Y axis.

Each dataset need to contain a label, and the data associated with it, additionally (only for scatterChart type) it can also define some labels for each specific unit of data (dataLabels)

{
    "fruits": {
        "labels": ["Q1", "Q2", "Q3", "Q4"],
        "datasets": [{
            "label": "Apples",
            "data": [100,50,10,70],
            "dataLabels": [
                "Full",
                "Medium",
                "Low",
                {
                    "value": "Medium",
                    // possible values are: "left", "right", "center", "top", "bottom"
                    "position": "left"
                }
            ]
        }, {
            "label": "Oranges",
            "data": [20,30,20,40]
        }]
    }
}

You can also pass some options to the chart that control the way the chart display, limit the information.

{{docxChart data=fruits options=options}}

the supported options are:

  • scales (object) -> Options to control the display of the chart axis
    • scales.xAxes (array) -> Options to control the display of the x axes
    • scales.yAxes (array) -> Options to control the display of the y axes Axis options
      • display (boolean) -> whether to show or hide the axis
      • ticks.stepSize (number) -> the step size to use to separate the axis's ticks
      • ticks.min (number) -> the min value to show in the axis's ticks
      • ticks.max (number) -> the max value to show in the axis's ticks
// example options
{
    "scales": {
        "xAxes": [{
              "display": true,
              "ticks": {
                  "stepSize": 2,
                  "min": 1,
                  "max": 15
              }
        }]
    }
}

docxWatermark

Create a watermark inside the desktop word application and use docxWatermark helper call inside the watermark text input. the helper is only needed when you want to configure options on the watermark with your logic, if you just want to modify the text and re-use the options you already applied to the word application then just use standard handlebars syntax.

watermark usage

watermark helper usage

The helper call in the text input can look like this:

{{docxWatermark text=watermark style=watermarkStyle}}

With the following data on the input:

{
    "watermark": "CLASSIFIED",
    "watermarkStyle": {
        "fontFamily": 'Times New Roman',
        "fontColor": '#c45911',
        "fontSize": 66,
        "fontBold": true
    }
}

The parameters that docxWatermark helper supports are the following:

  • text (string) required -> the text to display in the watermark
  • enabled (boolean) -> whether to display the watermark or not, it is true by default
  • style (object) -> options to control the styles on the watermark
    • fontFamily (string) -> the font family to use for the text shown. Example: Times New Roman
    • fontColor (string) -> the color to use for the text shown. it can be any css hex color, it also support color names but for better compatibility use hex. Example: #c45911
    • fontSize (number) -> the font size in number of points. Example: 66
    • fontBold (boolean) -> whether to use bold in text or not
    • fontItalic (boolean) -> whether to use italic in text or not
    • transparency (string) -> the percentage of transparency to use for the text, it can be anything between 0% and 100%. Example: 65%
    • orientation (string) -> the orientation to use for the text, it can be horizontal or diagonal. Example: diagonal

Automatic sync of Table of Contents

A docx document requires to always refresh the TOC to keep it in sync with the content/titles of the document. This presents an issue when you generate the content/titles of the document dynamically, because when you open the docx file you will noticed that the generated TOC is out of sync with what the document contains. To help with this we automatically update the TOC when producing the docx file, we do our best to produce the same result as you would get by refreshing manually just keep in mind that even if the styles don't match the TOC at least should have the same items/titles as the document. Page numbers in the TOC is something that we can not sync automatically, so by default when we detect there is TOC in the document we add a setting in the file that makes MS Word prompt and ask if you want to sync the TOC (fields, and page numbers) when you open the document for the first time. In case you find such prompt to be annoying then you can avoid such setting to be adding by using the docxTOCOptions helper with updateFields param in the TOC heading, you can pass false to this param to avoid the prompt.

watermark usage

Forms

The form elements like checkboxes and inputs can be placed to the word file from the Developers tab. This tab is by default hidden so you need to enable it using:

File tab, go to Options > Customize Ribbon Under Customize the Ribbon and under Main Tabs, select the Developer checkbox.

Text input

No need to use a special helper. Just add a text box and use handlebars syntax inside to fill a dynamic value.

Checkbox

Add checkbox control from the Developer tab, select Properties and use docxCheckbox helper call in the title. The only supported param is value which expects bool to toggle the checkbox.

{{docxCheckbox value=ready}}

Combobox

Add combobox control from the Developer tab, select Properties and use docxCombobox helper call in the title.

{{docxCombobox value=val}}

In case your items are static, you can prepare them upfront in the "Drop-Down List Properties" and use just a single parameter value to preselect desired items.

In case your items are dynamic, you can bind them using items parameter. This parameter expects the following array: [ { value: "a", text: "Some text to select" } ...]

{{docxCombobox value=val items=items}}

docxPageBreak

Add a forced page break to the document.

{{docxPageBreak}}

docxRaw

Allows to insert raw xml into the document, replacing some parent xml element. Intended to be used for advanced users which know how to manipulate the raw xml representation of a docx file

{{docxRaw xml="<w:r><w:t>raw xml run</w:t></w:r>" replaceParentElement="w:r"}}

Custom helpers

You can implement also your own custom helpers and use them in the word templates. The helpers section can be toggled in the studio using the "show helpers" button.

docx helpers

Child templates

The recipe doesn't support using child templates or assets to insert another docx file into one template. Both can be used just to insert text.

Development

Repetitive uploading of the docx template can get easily tedious. Fortunately, you can use the fs store external editor editing feature with docx as with any other file. The first you need to change the configuration to enable automatic files reload on external changes.

"extensions": {
  "fs-store": {
    "externalModificationsSync": true
    }
  }
}

Afterward, make sure you have ready a template with docx recipe and associated docx template in the studio. Then open a word application (the best is on the second screen) and find file data/adocxtemplate/content.docx representing your associated template. Now, editing and saving this file in word app cause automatic reload of the template in the studio and re-render so you see immediately the reflected changes.
