Excel Workspace

What is Excel Workspace?

Excel Workspace opens a multi-sheet .xlsx entirely in your browser — switch between sheets, profile columns, build an instant dashboard, combine sheets, and export to CSV, JSON, or a fresh .xlsx. Nothing is uploaded, so it's safe for confidential workbooks.

Frequently asked questions

How do I use Excel Workspace?

Paste or drop your data into the workspace, adjust the options to fit your data, then copy or download the result. Open multi-sheet Excel — browse, profile, visualize, and export each sheet.

Is my data uploaded or stored anywhere?

No. Everything runs locally in your browser — your data is never uploaded to a server. Nothing is sent to a server, so it's safe to use with private or sensitive data.

Is Excel Workspace Converter free?

Yes — it's completely free with no account, no sign-up, no watermark, and no daily usage limits.

What's the maximum file size?

There's no hard limit imposed by the tool. Because processing happens in your browser, the practical ceiling is your device's available memory — most everyday files work instantly.

Do I need to install anything?

No installs and no extensions — it runs entirely in your web browser and even works offline once the page has loaded.
