What this converter does

Local by design

File bytes stay inside your browser. DropConvert’s servers never receive or process them.

Conversion details

The first row becomes field names. Quoted fields, commas and line breaks are handled by Papa Parse.

Limits

Up to 10 MB. Duplicate or missing header names and malformed rows are reported instead of silently guessed.
