The formats
CSV and TSV at a glance
What is a CSV file?
CSV stores a table as plain text, one row per line, with commas between the columns. Almost every spreadsheet, database, and analytics tool can import and export it, which makes it the default format for moving data between systems. It has no formatting, formulas, or multiple sheets. It opens in Excel, Google Sheets, Numbers, LibreOffice Calc, any text editor, and practically every database and programming language.
What is a TSV file?
TSV is like CSV but separates columns with tab characters instead of commas. Because tabs rarely appear inside data, TSV files need less quoting, and you can paste them straight into a spreadsheet. Data science and bioinformatics tools use it often. It opens in Excel, Google Sheets, Numbers, LibreOffice Calc, text editors, and data tools.
Good to know
What changes when you convert CSV to TSV
- The first row is used as column names, and the delimiter is detected automatically, so semicolon-separated files from European versions of Excel work too.
- Fields that contain commas, tabs, quotes, or line breaks are quoted correctly.
- Very large files, in the hundreds of megabytes, may be slow, and the preview shows only the beginning.
FAQ
Questions, answered
Is this CSV to TSV converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. The conversion runs inside your browser with open-source CSV, JSON, YAML, XML, and Excel libraries, so your files never leave your device. Once the page has loaded, it even works offline.
Can I paste CSV instead of uploading a file?
Yes. Paste CSV text onto the page and it's converted the same way. Nothing you paste leaves your browser.
Can I convert several CSV files at once?
Yes. Add as many as you like. They're converted one after another, and you can download each TSV file as soon as it's ready or all of them in one ZIP file.
Does it work on iPhone, Android, Mac, and Windows?
Yes. It works in Chrome, Edge, Firefox, and Safari, on computers and phones.
What can open a TSV file?
Excel, Google Sheets, Numbers, LibreOffice Calc, text editors, and data tools.
Is there a file size limit?
There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and most computers handle files of a few hundred megabytes.
