About this conversion
Converting CSV to TSV replaces comma delimiters with tabs, producing a format where commas in data values cause no quoting complications. TSV is preferred when your data frequently contains commas — addresses, descriptions, monetary values formatted with thousands separators, or any free-text fields where CSV quoting rules add parsing complexity.
Common use cases include exporting data for bioinformatics pipelines that expect tab-delimited input, compatibility with legacy systems that parse tabs rather than commas, and working with Unix command-line tools like cut, awk, and paste that handle tab-delimited data naturally. Any value in your CSV that contains a tab character is automatically quoted in the TSV output.
Frequently Asked Questions
What is TSV format?
TSV (Tab-Separated Values) is similar to CSV but uses tab characters as delimiters — useful when data values contain commas.
Is my CSV data private?
Yes — completely. Your file is never uploaded to any server. All conversion happens inside your browser using WebAssembly — locally, with no upload. Once you close the tab, nothing is retained.
What is the maximum file size?
The free limit is 50 MB. For larger files, performance depends on your device's available memory — most modern machines can handle 500 MB to 1 GB comfortably.
What is the difference between CSV and TSV?
CSV uses commas as delimiters and is the most widely supported tabular format. TSV uses tabs and is preferred when data values frequently contain commas.
