About Converting TSV to CSV
TSV is like CSV but uses tabs as the column delimiter, which avoids problems when data itself contains commas. It is common in scientific and database exports. When you need to move away from TSV, the usual reason is simple: no formatting or formulas.
Converting your TSV spreadsheet to CSV solves that. CSV is a plain-text table format where each line is a row and commas separate columns. Its simplicity makes it the universal exchange format for data between spreadsheets, databases and code. In practice you gain readable by virtually every tool and tiny, plain-text files. PrivConvert runs the whole TSV-to-CSV conversion in server memory and deletes your file the instant the CSV is ready — nothing is stored, logged or reused.
When this conversion helps
- You need readable by virtually every tool
- You need tiny, plain-text files
- You need ideal for data import/export
- Sharing a TSV spreadsheet with someone whose software expects CSV
Tips for best results
- After converting, open the CSV and skim the formatting — complex layouts occasionally need a small touch-up.
- Files up to 250 MB are supported, and you can batch-convert several TSV files at once; each is processed privately and deleted immediately.

Drag and drop your file into the upload area, click to browse your device, or paste a URL to a file hosted online. You can upload files up to 250 MB and batch convert up to 20 files at once.
Once uploaded, the conversion from TSV to CSV starts automatically. The process runs entirely in an isolated environment - your data never leaves the secure pipeline.
Your converted file is ready instantly. Click the download button to save it to your device. The file is deleted from memory immediately after download.
Private by design, not as an afterthought
Most online converters upload your files to a server, keep them for days, and may mine them for AI training or resale. PrivConvert was built the opposite way — around your privacy.
Runs in any modern browser on Windows, macOS, Linux, Android and iOS — no install, plugin or desktop software needed.
Each job runs in an isolated in-memory sandbox, so most conversions finish in seconds instead of waiting in a queue.
We never keep a copy. Once your CSV is delivered, both the original and the result are gone — there is nothing left to leak or misuse.
Every conversion runs in its own locked-down process with no network access, so files can never leak or interfere with one another.
