Which placeholder formats are supported?

The tool supports {{name}}, ${name}, and > syntax within your DOCX template.

Can I process multiple records at once?

Yes, by providing an array of objects in the Merge Data JSON field, the tool will generate a document for each entry and combine them into one PDF.

What happens if I provide a single object instead of an array?

The tool will generate a single PDF document based on that specific record.

Is the output always a PDF?

Yes, the tool uses LibreOffice to render the final merged document into a PDF format.

Are there limits on the template file size?

The tool supports file uploads up to 100MB.
