What is CSV Stats?
Quick data profiling without opening a spreadsheet. Numeric stats only compute for cells that parse as numbers; non-numeric columns show em-dashes for those fields. Great for sanity-checking imports and spotting anomalies.
FAQ
- How does it decide which columns are numeric?
- Each cell is attempted as a float. Cells that fail to parse don't contribute to numeric stats. A column with mixed numeric and non-numeric cells still shows min/max/mean from the numeric subset.
- Can I download the statistics results?
- Yes. You can copy the stats table to your clipboard or download it as a CSV file for use in spreadsheets or reports.
- Is my CSV file safe on this tool?
- Completely safe. All processing happens locally in your browser—your CSV file never leaves your device or gets uploaded to any server.
