Frequently Asked Questions

Is it safe to process sensitive TSV files online?

Yes. Your TSV data is processed entirely within your browser. No data is ever sent to a cloud server, making it impossible for your information to be stored, sold, or leaked. It's as secure as opening a file in a local desktop application.

Can I open large TSV files in a browser?

Yes. Because processing happens locally, you're only limited by your device's available memory (RAM). Since there's no cloud upload, you're not restricted by internet bandwidth or server-side file size caps.

Why is this TSV tool faster than other online converters?

Traditional tools require you to upload your TSV file to a remote server, wait for processing, and then download the result. Tabularly uses DuckDB-Wasm to process data locally in your browser. This eliminates network latency and server wait times, resulting in instant processing for even large datasets.

Do I need to sign up to use the TSV tool?

No. You can access all browser-based features immediately without creating an account or providing an email address. Our goal is to make high-quality, private data tools accessible to everyone.

Can I save my filtered results back to my device?

Yes. Once you have filtered, queried, or converted your data, you can export the results as a clean file at no cost. This is an efficient way to prune massive datasets into manageable local files.

Can I use this converter without an Internet connection?

Yes. Once the page has loaded, the data engine runs entirely offline in your browser. Since no data is transmitted to a server, you can continue to analyze your TSV files even if you lose your Internet connection.

Privacy Note: This tool is safe for sensitive data because your files never leave your computer.
