security tips

🛡️

Opening an unexpected .xlsx in Excel can trigger macros; this viewer just reads the data, with no macro execution.

🔒

Because the file is parsed locally, you avoid uploading a potentially sensitive or malicious file to a third party.

👀

Preview the contents first, then decide whether to open it in a full spreadsheet app.
