How to replace newlines with commas

  1. Paste your list into Input, one item per line. A column copied from Excel or Google Sheets works as it is.
  2. The result is already joined with commas. Turn off Trim lines if spaces around items matter.
  3. Copy the comma-separated line and paste it where you need it.

From a column to a comma-separated line

Spreadsheets, databases and many forms want a list as one line, like London, Paris, Berlin. When you copy a column from Excel or Google Sheets, though, every cell arrives on its own line. This page replaces each of those line breaks with a comma, trims stray spaces from the start and end of each item, and drops blank rows, so the result is ready to paste.

Where a comma-separated list is useful

  • Email “To” and “CC” fields, which accept addresses separated by commas.
  • SQL queries such as WHERE city IN (…), after quoting each value.
  • Tag fields in CMSs and online stores that expect tag1, tag2, tag3.
  • Pasting a list into a single spreadsheet cell or a CSV field.
