Input and output
Example: `red\nblue` can become a correctly escaped CSV column with an optional header.
List to CSV Converter
Make a standards-correct one-column CSV locally. This is not simple comma joining.
Values are processed only in this browser. Formula-like values are preserved unchanged; use care when opening any CSV in a spreadsheet.
Using this tool
Convert a line list to CSV
Make a one-column CSV from one item per line, with controls for header, delimiter, line ending, and Excel BOM.
Important behaviour
Values are quoted when the CSV rules require it, so commas and quotation marks remain valid data.
Keep in mind
This route produces a single column rather than inferring a multi-column table.
Conversion is performed in the browser. Copying or downloading happens only when you choose those actions.
