What it does

Replaces inline string and number literals in your query with the placeholder style of your driver — ?, $1…$N, or :p1…:pN — and emits the extracted values as an ordered list you can paste into the bind step.

Limits

This is a regex-aware tokenizer, not a full SQL parser. It will replace values inside VALUES lists, WHEREcomparisons, and function arguments. Identifiers (table/column names) are left alone.
