Comma Separator
Paste numbers or words separated by spaces, tabs, or newlines and get a clean comma-separated list — with optional quotes, dedupe, sorting, and array wrapping for SQL IN clauses or code.
About this tool
You copied a column of IDs out of a spreadsheet or a query result, and now you need them as a single comma-separated line for a SQL IN clause, a code array, or a CSV cell. Doing that by hand is tedious and easy to get wrong. This comma separator takes values split by spaces, tabs, or newlines and joins them into one clean line in a moment.
Beyond the basic join, it covers the follow-up steps you usually do next: wrapping each value in quotes for string lists, removing duplicates, sorting, and bracketing the whole thing into an array. That turns a raw column into a ready-to-paste IN (...) list or a language literal without extra editing.
How to use
- Paste your values — one per line, or separated by spaces or tabs — into the input.
- The comma-separated result appears immediately in the output panel.
- Turn on quotes if you need each value wrapped for a string list.
- Enable dedupe to drop repeated values, and sort if you want them ordered.
- Switch on array wrapping to surround the list with brackets for code.
- Copy the final line and paste it into your query, script, or config.
Features
- Accepts input separated by newlines, spaces, or tabs interchangeably.
- Optional quoting for building string lists safely.
- Deduplicate values so a messy paste becomes a distinct set.
- Sort output for readable, predictable lists.
- Array wrapping for SQL IN clauses and code literals.
- Trims stray whitespace from each value automatically.
- Everything runs locally — your list never leaves the browser.
Frequently asked questions
Is my pasted list sent to any server?
No. The tool processes your input entirely in the browser with JavaScript. IDs, emails, or any values you paste stay on your machine.
Can it build a SQL IN clause directly?
Yes. Enable quoting for text values and array wrapping to get output like ('a', 'b', 'c'), which drops straight into an IN (...) clause. For numeric IDs you can skip the quotes.
What separators does it recognize in the input?
It splits on newlines, spaces, and tabs, so a column pasted from a spreadsheet or a space-separated line both work without any manual cleanup.
Does dedupe preserve order?
Deduplication keeps the first occurrence of each value. If you also enable sorting, the final list is ordered after duplicates are removed.
Will it remove empty lines and extra spaces?
Yes. Blank entries are dropped and surrounding whitespace is trimmed from each value, so you do not get stray empty items or padded entries in the result.
