About this tool
TSV to CSV Converter swaps between tab-separated and comma-separated representations of tabular data. It is handy when one application expects TSV exports while another only imports CSV, or when you need to transform clipboard data copied from a spreadsheet.
Features
Bidirectional conversion, proper quoting for fields with special characters, UTF-8 support, file upload, live preview, and downloadable output. The tool handles ragged rows gracefully and reports problems instead of producing malformed data.
Use cases
Preparing data for tools with strict format requirements, converting clipboard snippets from Excel into CSV for source control, and cleaning up exports from databases before importing them into other systems.
Why choose this tool
All processing happens locally in your browser, keeping proprietary spreadsheets private. The attention to quoting edge cases means you can trust the output even when rows contain commas, newlines, or Unicode punctuation.
FAQ
- How are embedded commas handled?
- Fields containing commas, quotes, or newlines are automatically wrapped in double quotes when converting to CSV.
- Does it support UTF-8?
- Yes. Unicode characters including Japanese text are preserved across conversion in both directions.
- Can I upload a file?
- Yes. Drag and drop a .tsv or .csv file onto the page to load its contents into the editor.
