CSV / TSV ConverterUser Guide
Convert delimiters between CSV and TSV, preserving leading zeros, whitespace, quotation marks, and cross-line fields; preview the table before exporting a copy.
How to use
Paste original text or import a single UTF-8 .csv/.tsv file.
Specify source and target delimiter formats, line breaks, and BOM, and check field previews.
Read formula style field reminders and export a full CSV or TSV.
Formats and limits
Maximum 2 MiB, 10,000 columns, 200 columns; the preview only displays the first 50 columns and 20 columns, and the export retains the complete data.
Strictly check the syntax of quotation marks and reject all entries with errors; do not guess numbers or dates, nor modify the content of formulas or formats without modification.
Output
CSV or TSV text copy.
Frequently asked questions
Will leading zeros or formulas automatically become spreadsheet format?
No. The tool retains field text and reminds formula styles; other spreadsheet software may still interpret it on its own after opening it, so please check the import options of that software.
