A CSV file is plain text with one row per line and values separated by commas. It is the format most systems export, and it is awkward to read as raw text. This page shows it as a grid instead.

- Read it as a tableEach line becomes a row. Scroll, search and sort the columns.
- Export if neededSave a copy in another format, or open it in the editor to change cells.
Good to know
A CSV file stores no formatting, formulas or multiple sheets, only text. If accented letters look wrong, the file was probably saved in a different text encoding than the one it is read with. Values that look like long numbers or dates are best checked against the original export.
