Frequently asked questions
Can I open an Excel file without Microsoft Office?
Yes, drop the spreadsheet into the viewer and it renders instantly in your browser, no Office license or installation needed.
Is it safe to view sensitive files here?
Yes, all processing happens locally in your browser, so files are never uploaded to a server and stay on your device.
What file types can the Universal Viewer open?
PDF, Word, Excel, CSV, JSON, and common media files — six-plus formats without switching apps or installing anything.
Is there a file size limit for viewing documents?
There's no hard cap enforced by the tool itself, though very large files may take longer since everything renders on your device.
Can I view a file on my phone?
Yes, it works in any modern mobile browser the same way it does on desktop, with no app to download.
What happens if I upload a corrupted or unsupported file?
The viewer shows an error instead of a preview rather than guessing at broken content, so you know right away to try a different file.
