JSON Formatter Compact

Purpose & User Intent: The tool targets developers, API integrators, and data engineers who need to reduce JSON payload size without altering data types or structure. It is used when bandwidth is limited, logs must stay concise, or inline examples require compact payloads.
Core Logic & Features: Required: strict JSON parsing, minification via whitespace removal outside string literals, and a single-line output that preserves types and structure. Top-level objects and arrays are supported. Optional/Advanced features include input size validation and diagnostic metadata for internal debugging; there is no UI styling or formatting beyond the minified result.
Inputs & Outputs: Input is a single text field containing JSON; Output is a compact JSON string. Validation ensures the input is well-formed JSON. Sample input: {"a":1,"b":[true,false]} → {"a":1,"b":[true,false]}.
Algorithms & Calculations: Parse the input using a strict JSON parser, then stringify the parsed object without extra spaces or line breaks. Maintain the order of keys; do not alter values or data types.
Error & Edge Cases: Invalid JSON yields a parse error with location guidance. Empty input or extremely large payloads trigger corresponding errors. Unicode is preserved; no comments or trailing commas are allowed.
Industry/Region & Localization: Standards follow RFC 8259 JSON, UTF-8 encoding. No locale-specific number or date formatting is applied.
Assumptions & Exclusions: Assumes input is strictly valid JSON. It does not support JSONC, comments, or custom pretty printing; formatting options other than minification are out of scope.
