Frequently asked questions

Can I edit cells without Excel?

Yes. Double-click any cell to edit it inline. Changes are tracked with full undo/redo (Ctrl+Z). Export the modified file when you're done.

Is it free forever?

Yes — completely free, no account required, no hidden paywalls.

What can I do that Excel can't handle?

Large CSV Viewer handles files with millions of rows, provides regex search, per-column type detection, and DuckDB-powered server-side queries — all things Excel cannot do on large datasets.

Does it work without internet?

You need an internet connection to upload the file to our processing server. Once loaded, basic navigation is fast — but the server connection is required for filtering, sorting, and export.

Can I use it on a Mac or Linux machine?

Yes. Since it runs entirely in the browser, it works identically on Windows, macOS, Linux, and Chrome OS.
