FAQ
What happens during XLSX to CSV conversion?
The converter exports one sheet into flat CSV text, which keeps values but drops spreadsheet-only features.
Are uploaded files kept permanently?
No. The planned pipeline keeps files for a short retention window and serves downloads through expiring links.
Can quality or formatting change?
Yes. Each converter page calls out what is preserved, what may be lost, and which settings matter before upload.
