FAQ
Questions about this tool
Why does my CSV open in one column?
The application probably expects a different delimiter than the file uses.
Are separators inside quotes replaced?
No. Parsing distinguishes field separators from punctuation inside quoted values.
Can I convert CSV to TSV?
Yes. Choose tab as the output delimiter and download a .tsv file.
