What is Comma Separated List?
Spreadsheets, ad platforms, and API fields often want comma-separated values — but your source is a space-separated paste from a doc or one item per line from a crawl. ToolYour Comma Separate splits input by whitespace, lines, or existing commas (normalize mode), optionally dedupes and trims, and returns a clean CSV-style string you can paste into Ads, Sheets, or CMS tags.
Honest limits: Items containing commas inside quoted phrases may need manual cleanup — this tool is for simple token lists (tags, keywords, IDs), not full RFC CSV with embedded commas in fields. Everything runs in the browser for the smoke-check; no signup.
Same job via REST (POST https://api.toolyour.com/api/v1/text-utilities/comma-separate) and MCP (comma_separate_post) on one API key.
What are common questions about Comma Separated List?
Auto vs lines vs CSV mode?
Auto splits on whitespace. Lines treats each row as one item. CSV normalizes an already comma-separated paste (spacing/dedupe).
Can I remove duplicates?
Yes — enable Remove duplicates when merging keyword lists from multiple sources (case-insensitive).
Is this a full CSV editor?
No. It joins simple tokens with commas. Quoted fields with commas inside them need a spreadsheet or dedicated CSV tool.
Where do I sort or diff lists next?
Use Sort Lines before joining, or Compare Texts in lines mode to diff two lists.
REST API and MCP?
REST: JSON body with text (and optional mode, dedupe, trim) to https://api.toolyour.com/api/v1/text-utilities/comma-separate. MCP: comma_separate_post or plan_task for “add commas to list” at https://api.toolyour.com/mcp.
