Does Excel Analyzer upload my files or code?

No. Ordinary processing happens inside your browser. Python execution runs in an isolated browser worker, while imported files stay on your device.

Can I import and export files with Excel Analyzer?

You can import an XLSX workbook and download the resulting analysis.

No. Tools that execute Python load a WebAssembly-based Python runtime in the browser. The first run may take longer while that runtime downloads.

COMMON QUESTIONS

Does this upload my code or files?

No. Processing happens locally in your browser. Runtime tools download Python itself, but your source is not sent to our server.

Why can the first Python run take longer?

The browser downloads and starts the Python WebAssembly runtime. Later runs in the same tab are normally much faster.

Can I stop a program that takes too long?

Yes. Runtime tools show a Stop button while Python is working. Stopping terminates the isolated worker and a clean runtime starts when needed.
