About the CSV to TSV Converter
Convert CSV to TSV online for free, with no account and no watermark. CSV has no formatting, no sheets and no data types, so switching to TSV is the quickest way to get tab-separated data that pastes cleanly for pasting data into spreadsheets, bioinformatics and data with commas inside values.
Spreadsheets are read and written with SheetJS, the open-source spreadsheet engine used by thousands of data apps, so every sheet, row and value is handled accurately. Because everything happens on your own device, your data files are never uploaded, stored or seen by anyone else, which makes it safe for customer lists, salary sheets, GST data and API exports.
What to expect: the delimiter and text encoding are detected automatically; formulas are exported as their calculated values, while text such as PIN codes and phone numbers with leading zeros stays intact.
How to use the CSV to TSV Converter
- Click "Choose files" or drag your CSV data files onto the box. You can add several at once.
- Choose whether to convert all sheets or only the first one.
- Press "Convert to TSV". The conversion runs on your device and shows its progress.
- Download each TSV file, or use "Download all (ZIP)" when you converted several.
- Open the result in Excel or Google Sheets to check it; your original CSV is never changed.
Tips & benchmarks
- Tabs inside cells are replaced with spaces so the columns always line up.
- To open the file in Excel with Hindi or ₹ characters intact, use Data → From Text/CSV and choose UTF-8; the file includes a UTF-8 marker for this.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the TSV to a website or government portal.
Frequently asked questions
How do I convert CSV to TSV?
Click "Choose files", select your CSV data files, adjust the options if you want, and press "Convert to TSV". The TSV downloads immediately; with several files you can download everything as one ZIP.
Is this CSV to TSV converter free and safe?
Yes. It is completely free, with no sign-up, no daily limit and no watermark. The conversion runs inside your browser, so your data files never leave your phone or computer and nothing is stored on News Appite's servers.
Are formulas, formatting and all sheets kept?
Every sheet is converted (or only the first, if you choose). Formulas are exported as their current values, and cell colours and fonts are not carried over because formats such as CSV, JSON and SQL cannot store them.

What is the difference between CSV and TSV?
CSV (Comma-Separated Values) is a plain-text table best suited to importing data into databases, CRMs, Tally, mailing tools and Python or R. TSV (Tab-Separated Values) is a plain-text table best suited to pasting data into spreadsheets, bioinformatics and data with commas inside values.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
How do I convert CSV to TSV in Excel?
Open the file in Excel via Data → From Text/CSV (choose UTF-8 for Hindi or ₹), then use File → Save As. This converter does it instantly and keeps leading zeros such as PIN codes.
How do I convert CSV to TSV in Python?

What is a CSV file?
CSV stores a single table as plain text, one row per line with values separated by commas. Every spreadsheet, database, CRM and programming language can import it, which makes it the universal format for moving data.
What is a TSV file?
TSV is like CSV but separates columns with tab characters. Because tabs rarely appear inside values, TSV avoids most quoting problems and pastes cleanly into Excel and Google Sheets.
