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.

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.

How does this compare to Excel for large TSV files?

Standard spreadsheet software often freezes or hits row limits when opening large TSV files. This tool handles millions of rows without slowing down, providing deeper statistical insights and faster filtering than traditional spreadsheet applications.

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.

Is there a cost to use this data tool?

No, this tool is completely free. There are no hidden fees, no credit card requirements, and no data harvesting. We provide these utilities to demonstrate the performance and privacy benefits of Tabularly's data workspace.
