Frequently Asked Questions

Can this tool parse CSV files with custom delimiters like tabs or semicolons?
Yes. You can select between Comma (`,`), Semicolon (`;`), Tab (`\t`), and Pipe (`|`), and toggle automatic type coercion for numbers and booleans.
Is my CSV data uploaded to any remote server?
No. All CSV parsing and JSON transformation happens locally in your browser memory using Web APIs. Your confidential spreadsheet data never leaves your device.
