About the CSV viewer
This CSV viewer turns a comma-separated file into a clean, sortable, searchable table. Paste CSV text or upload a .csv file and it parses the rows (handling quoted fields) and displays them. Click a column header to sort, and type in the search box to filter. The file is parsed in your browser and never uploaded.
How CSV Viewer works
How to view a CSV
- Upload a .csv file or paste CSV text.
- The first row is treated as the header.
- Click a header to sort, or type in the search box to filter rows.
Quoted fields
The parser understands quoted values, so commas and quotes inside fields are handled correctly — not just naive comma splitting.
Private and fast
Everything happens in your browser, so even sensitive spreadsheets stay on your device. Large files display smoothly with a scrollable, sticky-header table.
