How do I convert text lines to a comma list?

Paste your list (one item per line) and the comma-separated output appears instantly. Click Copy.

When should I use this?

Use it when building SQL IN clauses (WHERE id IN (1, 2, 3)), creating CSV data from line-by-line exports, preparing comma-separated input for APIs, and converting a bullet list to a single-line format.

Can I use a different separator?

The default output uses comma + space (", ") between items. For other separators, use the Find and Replace tool to swap the commas after converting.

What if my lines have extra spaces?

The tool trims whitespace from each line before joining, so " item " becomes just "item" in the output.

What Is Text to Comma List?

Convert a list of items (one per line) into a single comma-separated list.

Converting a line-by-line list into a comma-separated value (CSV) format is a constant need when moving data between different systems. A list of email addresses, product names, or database IDs might arrive one item per line (from a spreadsheet column or text file), but need to be formatted as a single comma-separated string for a SQL IN clause, a bulk email input field, or an API request parameter.

This tool performs this conversion instantly — joining all lines with a comma and space to produce a clean, ready-to-use single-line output. Leading and trailing whitespace is trimmed from each item automatically.

Apple
Banana
Orange

When to Use the Text to Comma List

→Building SQL IN clauses — "SELECT * FROM users WHERE id IN (1,2,3,4,5)" requires comma-separated IDs; convert a line-by-line ID list for direct SQL use
→Preparing bulk email inputs — some email platforms accept comma-separated recipient lists; convert a line-by-line address list in one click
→Building API request parameters — many APIs accept comma-separated lists for filtering, field selection, or multi-value parameters (?ids=1,2,3)
→Converting a pasted spreadsheet column to a single line — copying a spreadsheet column gives one value per line; this converts it to a compact CSV string
→Preparing tag input fields in CMS — content management systems that accept comma-separated tags need lists in comma-delimited format
