Turn a list into a SQL IN clause
Building a SQL IN clause from a list of values means quoting and comma-separating them correctly, which is tedious and error-prone. This tool converts a list of values into a SQL IN () clause with smart quoting for strings.
Why smart quoting matters
A SQL IN clause needs its values comma-separated inside parentheses, and strings must be quoted while numbers must not, and a stray quote or missing comma breaks the query. Building it from a pasted list, with the tool quoting strings and leaving numbers bare, produces a correct clause ready to drop into a query. This is exactly the kind of formatting that is quick to get wrong by hand across a long list, and getting it wrong means a syntax error or, if you quote wrongly, a query that runs but returns nothing. The tool handles the quoting so the clause is correct.
A correct clause, fast
It runs entirely in your browser, so nothing you paste is uploaded and the result is yours to copy straight into a project, which lets you work on private code and data without anything leaving your machine.

Frequently Asked Questions
What does it build?
A SQL IN () clause from a list of values, with the values comma-separated inside parentheses and strings quoted correctly.
Why does quoting matter?
Because strings must be quoted and numbers must not. A stray quote or missing comma breaks the query, or a wrongly-quoted value makes it return nothing.
What is smart quoting?
The tool quotes string values while leaving numbers unquoted, producing a correct clause without you deciding each value by hand.
When is this useful?
Building a query that filters by a list of values, where hand-quoting a long list is slow and error-prone.
Is my data uploaded?
No. The tool runs entirely in your browser.
