Types of tags

The syntax is inspired by Mustache. The template is created in Microsoft Word or other software that can save a docx.


With this template (input.docx):

Hello {name} !

And given the following data (data.json):


docxtemplater will produce (output.docx):

Hello John !


Conditions start with a pound and end with a slash. That is {#hasKitty} starts a condition and {/hasKitty} ends it.

{#hasKitty}Cat’s name: {kitty}{/hasKitty}
{#hasDog}Dog’s name: {dog}{/hasDog}

and this data:

    "hasKitty": true,
    "kitty": "Minie"
    "hasDog": false,
    "dog" :null

renders the following:

Cat’s name: Minie

For a more detailled explanation about Conditions, have a look at Sections

You can also have “else” blocks with Inverted Sections


In docxtemplater, conditions and loops use the same syntax called Sections

The following template:

    {name}, {price} €

Given the following data:

    "products": [
        { name :"Windows", price: 100},
        { name :"Mac OSX", price: 200},
        { name :"Ubuntu", price: 0}

will result in :

Windows, 100 €
Mac OSX, 200 €
Ubuntu, 0€


A section begins with a pound and ends with a slash. That is {#person} begins a “person” section while {/person} ends it.

The section behaves in the following way:

Type of the value the section is shown scope
boolean once if true unchanged
falsy or empty array never  
non empty array for each element of array element of array
object once the object

This table shows for each type of value, what is the condition for the section to be changed and what is the scope of that section.

If the value is of type boolean, the section is shown once if the value is true, and the scope of the section is unchanged.

Example 1

If we have the section

    {price} €

Given the following data:

    "hasProduct": true,
    "price" : 10

Since hasProduct is a boolean, the section is shown once if hasProduct is true. Since the scope is unchanged, the subsection {price} € will render as 10 €

Inverted Sections

An inverted section begins with a caret (hat) and ends with a slash. That is {^person} begins a “person” inverted section while {/person} ends it.

While sections can be used to render text one or more times based on the value of the key, inverted sections may render text once based on the inverse value of the key. That is, they will be rendered if the key doesn’t exist, is false, or is an empty list. The scope of an inverted section is unchanged.


  No repos :(


  "repo": []


No repos :(

Sections and newlines

New lines are kept inside sections, so the template :

  No repos :(


  "repo": [{name: "John"}]
  "repo": [{name: "Jane"}]

Will actually render


(where NL represents an emptyline)

The way to make this work as expected is to not put unnecessary new lines after the start of the section and before the end of the section.

For our example , that would be :

{#repo} <b>{name}</b>
{/repo} {^repo} No repos :( {/repo}

Raw XML syntax

It is possible to insert raw (unescaped) XML, for example to render a complex table, an equation, ...

With the rawXML syntax the whole current paragraph (w:p) is replaced by the XML passed in the value.


with this data:

{rawXml:'<w:p><w:pPr><w:rPr><w:color w:val="FF0000"/></w:rPr></w:pPr><w:r><w:rPr><w:color w:val="FF0000"/></w:rPr><w:t>My custom</w:t></w:r><w:r><w:rPr><w:color w:val="00FF00"/></w:rPr><w:t>XML</w:t></w:r></w:p>'}

This will loop over the first parent <w:p> tag

If you want to insert HTML styled input, you can also use the docxtemplater html module : https://modules.docxtemplater.com/modules/html/

Dash syntax

When using sections, docxtemplater will try to find on what element to loop over by itself:

If between the two tags {#tag}______{/tag}

  • there is a tag <w:tc> , that means that your loop is inside a table, and it will loop over <w:tr> (table row).
  • by default, it will loop over <w:t>, which is the default Text Tag

With the Dash syntax you can specify the tag you want to loop on: For example, if you want to loop on paragraphs (w:p), so that each of the loop creates a new paragraph, you can write :

{-w:p loop} {inner} {/loop}
