SQL IN Clause Generator: List to IN (...) in One Click

This free tool turns a column or list of values into a ready SQL IN clause. It quotes text, leaves numbers bare, removes duplicates, escapes single quotes and can split very long lists into chunks.

What Is It and When Do You Need It?

Pasting a column of IDs into a query means adding quotes and commas to every line. That is slow and easy to get wrong, especially for hundreds of values.

Paste your list and copy a finished IN clause.

How to Use This Tool

  1. Paste the values, one per line.
  2. Choose how to quote them.
  3. Choose whether to remove duplicates and whether to split into chunks.
  4. Press Generate and copy the result.

How the Calculation Works

Each non-empty line is trimmed. In automatic mode, a value that looks like a number stays bare and anything else is wrapped in single quotes with inner quotes doubled. The values are joined with commas inside IN ( ... ). With chunking, several IN lists are joined by OR.

Worked Example

The lines apple, banana, O'Brien and 42 give IN ('apple', 'banana', 'O''Brien', 42).

Common Uses

  • Ad hoc queries from spreadsheets.
  • Data fixes and audits.
  • Reports on a list of IDs.
  • Cleaning pasted lists.

Tips and Common Mistakes

  • Use parameters in application code.
  • Check for hidden spaces in pasted values.
  • Use chunks for Oracle.

Next, you may need the Markdown table generator, string escape tool, query string parser, JSON to TypeScript.

Everything runs in your browser. Nothing you type is uploaded, stored or sent to any outside service.

Frequently Asked Questions

A single quote is doubled, which is the SQL standard way to escape it. O'Brien becomes 'O''Brien'.
Some databases, such as Oracle, limit an IN list to 1,000 items. Chunks are joined with OR so the query still works.
In automatic mode, plain numbers are left bare and everything else is quoted.
It escapes single quotes, but for application code you should always use parameterised queries instead.
