How to use SQL IN Clause Generator
- Paste one value per line; blank lines are ignored and surrounding whitespace is trimmed.
- Set the column name and choose text, integer or PostgreSQL parameter output.
- Generate and review the predicate; parameter mode also gives the ordered value array.
Build a predicate from a small lookup list
Text mode preserves leading zeros, apostrophes and backslashes through PostgreSQL escape-string literals. Integer mode validates the entire token and normalizes arbitrary-size integers without converting through a floating-point number. The column field is one quoted identifier, not an expression. Empty input produces FALSE instead of invalid IN () syntax. Values containing the word NULL remain strings in text mode.
Prefer parameters in application code
Parameter mode emits $1, $2 and so on plus a JSON array of string values to bind in the same order. Pass those values through your database driver instead of concatenating untrusted input. This tool targets PostgreSQL predicates and does not run SQL. A null column value follows SQL’s three-valued logic; this generator does not append IS NULL or invent null members from blank lines.

Can I paste comma-separated values?
Use one value per line. Commas can be part of a string and are preserved instead of being treated as separators.
Is input uploaded?
Processing takes place in your browser. This tool does not send your input or selected files to a conversion API.
