How the list to CSV converter works

Paste a list — one item per line — and press "Lines → Separated" to join it into a single string using whichever separator you pick: comma, semicolon, or pipe. Or paste an already-separated string and press "Separated → Lines" to break it back into one item per line.

Handy for moving data between formats — pasting names into a spreadsheet formula, building a SQL IN() list, or turning a CSV export back into a readable list.

Common uses

  • Building a comma-separated value for a spreadsheet formula or SQL query
  • Converting an exported CSV column back into a line-by-line list
  • Formatting a list of tags, emails, or IDs for a form field
  • Prepping a list for a script or API that expects one format or the other

FAQ

What separators are supported?
Comma, semicolon, and pipe ( | ). Pick the one you need from the dropdown before converting.
Does it trim extra spaces?
Yes — spaces around each item are trimmed automatically in both directions.
Is my data saved anywhere?
No. Conversion happens locally in your browser and nothing is uploaded.
