CSV Viewer & Editor

CSV Viewer & Editor opens comma-, semicolon- or tab-separated data as an editable table. It parses quoted cells correctly — including delimiters, line breaks and escaped quotes inside quotes — and lets you edit cells, add or delete rows and columns, rename and reorder columns, filter and sort before exporting CSV or TSV.

Opening a CSV in a spreadsheet can silently change it: leading zeros vanish, long numbers turn into scientific notation and formula-like cells may run. Editing it here keeps every cell as plain text, and safe export protects the people who open your file in a spreadsheet later.

1. Open a .csv or .tsv file, or paste the text into the box.
2. Leave the delimiter on Auto-detect or choose comma, semicolon or tab, then press Load into table.
3. Edit cells directly; use the column buttons to move, delete or rename columns, and Add row / Add column to grow the table.
4. Filter rows by text or sort by any column, ascending or descending.
5. Pick safe or raw export, then copy the CSV or download CSV or TSV.

• Auto-detection of comma, semicolon and tab delimiters, with manual override
• Correct handling of quoted cells, embedded delimiters, line breaks and "" escapes
• Full Unicode support, including Indian scripts and emoji
• Cell editing, add/delete rows and columns, rename and reorder columns
• Text filter and numeric-aware ascending/descending sort
• Safe export that neutralises formula-like cells, plus a clearly warned raw mode
• Limits of 20 MB, 100,000 rows and 500 columns, checked before the table is built

• Keep safe export on for files that people will open in Excel, LibreOffice or Google Sheets.
• Check the detected delimiter in the status line — European files often use semicolons.
• Turn off “First row contains column names” if your file has no header row.
• Clear the filter before exporting if you want every row in the file.
