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 run SQL SELECT statements on my files?

Yes. This is a full SQL playground, not just a simple filter. You can write and execute complex SELECT statements on your local files using DuckDB SQL syntax.

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.

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.

Do I need to install software to view TSV files?

No. This is a zero-install, browser-based utility. You can open, filter, and query TSV files immediately without installing Python, R, or other data tools. This is ideal for people on restricted work computers who can't install software without IT approval.

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.

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