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.

What is the difference between JSON, JSONL, and NDJSON?

Standard JSON is a single large object, whereas JSONL and NDJSON store each record on a new line. They're more efficient for large datasets because they can be processed as a stream. Our local engine can load even big files without crashing your browser.

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.

What technology powers this tool?

This local-first tool is powered by DuckDB-Wasm, a high-performance engine that runs natively in the browser via WebAssembly. This allows for complex SQL queries and data transformations at speeds comparable to native desktop software.

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.

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.
