Create Word Documents

This guide will take you through the process of populating Office DOCX templates with data. The resulting DOCX file can then optionally be converted into a PDF document.

Populating DOCX templates with data and converting DOCX files into PDF documents require special licenses. Contact Sales for more information.

General Principles

Word templating consists of the following elements:

A DOCX file that will be used as the template.
A template model that contains the placeholder values to replace in the DOCX template.
Configuration for the template/model.

Template Model

The template model must contain:

A configuration containing both a start and end delimiter. The default delimiters are { and }, and both can be configured in the request.
At least one placeholder-value pair. The placeholder name must correspond to the placeholder defined in the DOCX template.

Populating a Document

PSPDFKit supports replacing placeholder text strings, automatic reflow, loops, and dynamic tables.

Text Replacement

Consider the following DOCX content:

Hello my name is {name}.
There is {more}.

Use the following model:

"model": {
  "name": "Petey Eff",
  "more": "lorem ipsum dolor sit amet."
}

The outcome in the output DOCX document will be:

Hello my name is Petey Eff.
There is lorem ipsum dolor sit amet.

Loops

Consider the following DOCX content:

{ledger}:
{#items} {name} {price} {/items}

Here, items is the name of the loop, and name and price are placeholders for repetitive elements. Consider the following model:

"model": {
  "ledger": "Tom's groceries",
  "items": [
    { "name": "A", "price": 10 },
    { "name": "B", "price": 15 }
  ]
}

The outcome in the output DOCX document will be:

Tom's groceries:
A 10
B 15

Request Example with Custom Delimiters

This example performs dynamic population with custom delimiters ({{ and }}) using a request to the /api/process_office_template endpoint:

curl -X POST http://localhost:5000/api/process_office_template \
  -H 'Authorization: Token token=<API token>' \
  -H 'content-type: multipart/form-data' \
  -F 'document=@/path/to/template.docx'
  -F 'model={
    "config": {
      "delimiter": {
        "start": "{{",
        "end": "}}"
      }
    },
    "model": {
      "placeholder": "replacement value",
      "loop-name": [
        {
          "placeholder-within-loop": "replacement value",
          "another-placeholder-within-loop": "replacement value 2"
        },
        {
          "placeholder-within-loop": "another replacement value",
          "another-placeholder-within-loop": "another replacement value 2"
        }
      ]
    }
  }' \
  --output result.docx
