Frequently Asked Questions

Is it safe to process sensitive NDJSON files online?

Yes. Your NDJSON 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 NDJSON tool faster than other online converters?

Traditional tools require you to upload your NDJSON 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 NDJSON 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.

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 NDJSON files even if you lose your Internet connection.

Do I need to install software to view NDJSON files?

No. This is a zero-install, browser-based utility. You can open, filter, and query NDJSON 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.

Why use a local-first tool instead of a cloud converter?

Cloud converters require you to upload sensitive files to their servers, creating a privacy risk and slowing down the process with network transfers. This tool is private by design; all processing happens on your computer, so your data is never visible to any third party.
