Generate a SQL IN clause from a list
Paste a list of IDs or strings and get a ready-to-use IN (...) clause with correct quoting — and chunking when the list is too long for one statement.
Open the tool, then paste the sample input below. Everything runs locally in your browser.
The problem
You have a column of IDs from a spreadsheet or a log and need them in a SQL IN clause. Quoting each value and joining with commas by hand is tedious and error-prone, and very long lists exceed database limits. Generating the clause handles quoting and chunking for you.
Sample input
1001
1002
1003Expected output
WHERE order_id IN (1001, 1002, 1003)Numbers are left unquoted; string values would be wrapped in single quotes. For thousands of values, split into multiple IN clauses combined with OR.
How to do it
- Paste the list of values.
- Choose whether the values are numbers or strings.
- Set a chunk size for very long lists.
- Generate the IN clause.
- Copy it into your query.
Common mistakes
- Quoting numeric IDs, which can defeat an index.
- Not quoting string values, causing a syntax error.
- Exceeding the database limit on IN list length.
- Leaving duplicate or blank values in the list.
- Stray whitespace around values that breaks matching.

FAQ
How do I turn a list into a SQL IN clause?
Paste the values and generate the clause. The tool quotes strings, leaves numbers unquoted, and joins them with commas inside IN (...).
Should numeric IDs be quoted?
No. Quoting numbers can force a type conversion that defeats an index. Keep numeric IDs unquoted and quote only string values.
What if my list is too long for one IN clause?
Split it into chunks and combine them with OR, or load the values into a temporary table and join. The builder can chunk long lists for you.
Does it remove duplicates?
Deduplicate the list first, for example with the List Comparator, so the IN clause does not carry redundant values.
Is my list uploaded?
No. The clause is generated locally in your browser. Your values are not sent to a server.
The IN clause is generated locally in your browser. Nothing is uploaded.
