CSV Viewer & Explorer
Paste or upload a CSV or TSV and explore it as a real table: sort, filter, hide columns, read per-column statistics and export exactly what you filtered — all without the file leaving your browser.
CSV source
The delimiter is detected automatically from the first lines (comma, tab, semicolon or pipe) and can be overridden above. Headers are detected from a unique, non-numeric first row.
About this tool
CSV Viewer parses your file with a proper RFC-4180-style reader — quoted fields, doubled quotes, embedded delimiters and newlines, CRLF — then detects the delimiter and header row, infers each column's type and lets you sort, filter, hide columns and read real statistics before exporting the filtered result as CSV. The file is read with the browser's File API and processed locally, so nothing is uploaded. To keep the tab responsive the tool caps the work at 50,000 parsed rows, renders 200 rows at a time behind a “Show more” button, and refuses files over 5 MB.
