Generate PDF in Python

Overview

Apryse's office template generation framework enables the dynamic generation of PDFs:

  • You provide a template in the form of an Office document (such as .docx)
  • You provide replacement data in JSON form
  • Apryse SDK will efficiently generate a PDF by merging the data with the template
  • Fully featured, with support for loops, conditionals, images, table generation, etc.
  • Use your preferred office editor to design attractive templates, and Apryse will take care of the rest
  • All logic is entirely contained within the SDK, with no external dependencies

Easy to use

The generation framework requires minimal code to get up and running. Simply initiate a normal Office conversion, but with the optional TemplateParamsJson parameter set:

# Create a TemplateDocument object from an input office file.
template_doc = Convert.CreateOfficeTemplate(input_path, None)

# Fill the template with data from a JSON string, producing a PDF document.
pdfdoc = template_doc.FillTemplateJson(json_data_string);

# Save the PDF to a file.
pdfdoc.Save(output_path, SDFDoc.e_linearized)

Examples

The following are a series of real examples, generated using the code above. For each example, the template source and the json data source are included below, so that you can try them out yourself.

Simple text replacement (.docx, .json)

Tags in the template document are replaced with a string from the supplied JSON. To control the style of the text, simply modify the style of the template tag as desired:

{
	"short_text": "Lorem ipsum dolor, .etc"
}

Automatic reflow (.docx, .json)

Text reflows according to the rules set in the original template file, and will automatically generate extra pages if needed. Make use of column layouts and justification rules. This example uses a list loop with dynamic item renumbering.

{
	"legal_heading":"End-User Agreement",
	"legal_clauses": [
		{"legal_clause":"Sed ut unde omnis iste natus error sit volup tatem..."},
		{"legal_clause":"Lorem ipsum dolor sit amet, consec  tetuer adipi s..."},
		{"legal_clause":"pretium quis, sem. Nulla conse quat massa quis eni..."},
		{"legal_clause":"idunt. Cras dapibus. Vivamus elem entum semper nis..."}
	]
}

Dynamic tables (.docx, .json)

Dynamically insert or remove rows into tables using loops and conditionals. Table formatting such as row bands are updated. Especially useful for invoice generation.

{
	"items": [
		{"item": "Wireless", "charge": "$42.34"},
		{"item": "Long Distance", "charge": "$12.55"},
		{"item": "Data", "charge": "$14.89"}
	],
	"balance":"$12.52",
	"total_due":"$82.30",
}

Insert images (.docx, .json)

Insert images into the text at any location using the image_url value specifier. Images can be resized as desired, and inserted at any position in the original document.

{
	"logo":{"image_url":"./logo_red.png", "width":40, "height":40}
}

Reflow around figures (.docx, .json)

Automatically flow text around obstacles according to the template.

{
	"long_text": "Sed ut perspiciatis unde omnis iste natus..."
}
