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 this tool identify data quality issues in TSV files?

Yes. During the profiling process, the engine automatically detects null values, inconsistent data types, and potential outliers. This provides an immediate health check of your TSV data before you start your analysis.

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.

Is this tool compliant with strict corporate security policies?

Yes. This tool is ideal for environments with strict data sovereignty requirements. Since no data leaves your machine, using this browser-based utility is functionally equivalent to using a local text editor or spreadsheet application, bypassing the risks of third-party cloud uploads.

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.
