How to use CSV Viewer and Editor
- Paste CSV and choose whether the first row is a header.
- Select View CSV to open an editable table.
- Edit cells directly or select a heading to sort by that column.
- Download CSV and choose spreadsheet-safe export when opening untrusted values in spreadsheet software.
Example
Name,Note followed by Ava,"hello, world" displays the comma as part of one editable cell.
Limits and details
- The viewer accepts up to 500,000 characters, 5,000 rows, and 100 columns.
- Spreadsheet-safe export prefixes cells that could be interpreted as formulas; this changes those cell values on re-import.
Common questions
Does CSV quoting survive editing?
The download quotes cells when needed and doubles embedded quotes, preserving commas and line breaks.
Will safe mode change negative numbers?
No. A minus sign is escaped only when it begins a formula-like expression; ordinary negative numeric values remain numeric.
