Frequently asked questions

Is my file uploaded?
No. The conversion runs on your device.
What happens to fields that contain a comma?
They're quoted, and any quote characters inside them are escaped. This is the part a find-and-replace of tabs for commas gets wrong and silently corrupts.
Are line breaks inside a field preserved?
Yes. A field containing a newline is quoted so it stays one field rather than splitting into two rows.
Can I convert TSV to something other than CSV?
Yes — once the file is loaded, the Converter can also produce Excel, JSON, XML, YAML or Parquet from it.
