Frequently asked questions

Are my documents uploaded to a server?+

No. Everything runs in your browser. Your files never leave your device and are never sent to any server.

What placeholder format does it use?+

Use double curly braces like {{FirstName}} or {{Company}} in your Word template.

Can I use an Excel file instead of CSV?+

Save your Excel file as CSV first — the tool accepts .csv data files.

How many documents can I generate at once?+

One per row in your CSV — there is no fixed limit, but very large datasets may be slower depending on your device.

Does it preserve formatting from the template?+

Yes. Fonts, styles, tables, and layout from your .docx template are preserved in every output document.

Is Document Generator free?+

Yes, free for 5 uses per month with no signup. Upgrade to Pro for unlimited uses at €10/month.
