FAQ

What kind of file do I get?

A downloadable Excel (.xlsx) or CSV file, with charts where they help.

Do I need to provide data?

If you have data, upload it (Excel, CSV or PDF) and Ofox Chat organizes it with this template. If not, send it anyway to set up the structure first.

Can I edit the prompt?

Yes. The prompt goes into the Ofox Chat input box — swap in your own topic, add requirements or drop what you don’t need before sending.

Can I copy and use the prompt directly?

Yes. Tap “Copy” on the prompt card to get the plain text — it works in other AI tools too.
