Regex Tester & Validator

This PCRE regex with global and multiline flags is designed to match specific JSON-formatted configuration blocks, likely from an Autonote system. It captures the "ControlLabel", "ControlOptions" (specifically looking for the text "Select all that apply:"), and the "ControlType" (specifically "OneResponse"). It is highly useful for auditing or transforming survey configurations where a multi-select prompt is paired with a single-response control type.
