Frequently Asked Questions
Is my data secure?
Yes. Files under 500MB are processed entirely in your browser - they never leave your device. Larger files are uploaded to our secure servers for processing and automatically deleted after 24 hours. We don't read, analyze, or store your data beyond the temporary processing period.
Why can't Excel open my file?
Excel has a hard limit of 1,048,576 rows per worksheet. If your CSV has more rows, Excel simply won't open it or will truncate the data. Our viewer uses pagination to let you navigate through unlimited rows without loading everything into memory.
What's the maximum file size?
We support CSV files up to 10GB. Files under 500MB process instantly in your browser. Larger files are uploaded to our servers where they're processed using high-performance tools designed for big data.
Can I search across all pages?
Yes! For files processed on our server (files over 500MB), use the "Search All" button to search across your entire dataset. Results are returned instantly thanks to our indexed search system.
What CSV formats are supported?
We support standard CSV files with comma, semicolon, or tab delimiters. The parser automatically detects the delimiter and handles quoted fields, escaped characters, and various line endings (Windows, Mac, Linux).
💡 Pro Tips
- Click any cell to copy its value to your clipboard instantly.
- Use column filters to focus on specific values - great for finding anomalies in data.
- Hide columns you don't need to focus on what matters.
- Resume your session - if you close the tab, you can continue where you left off within 24 hours.
