About CSV Viewer
Quickly inspect a CSV without opening a spreadsheet app. The delimiter (comma, semicolon, tab, or pipe) is auto-detected, quoted fields with embedded commas and newlines are handled correctly, and the header row stays visible while you scroll.
Click any column header to sort — numbers sort numerically, text alphabetically. A summary shows the row and column counts at a glance.
Common uses
- Sanity-check an export before importing it elsewhere
- Find the largest or smallest values in a column
- Read a semicolon- or tab-separated file that Excel mangles
Limitations
- Rendering is capped at the first 1,000 rows to keep the page responsive; sorting still considers every row.
- This is a viewer — editing and saving are out of scope.
