JSON Key Quoter

This tool accepts JSON-like text that may lack quotes around object keys and outputs strictly valid JSON with properly quoted keys and preserved value types. It handles nested objects and arrays, producing either compact or pretty-printed results based on user settings. The core value lies in reliably cleaning data dumps, logs, and configuration snippets so they can be ingested by APIs or stored in databases. Conceptually, the tool performs tolerant parsing: it identifies unquoted keys, wraps them in double quotes, escapes strings as needed, and then re-serializes the structure to standard JSON. It avoids executing any code and does not perform semantic validation beyond syntax, ensuring safety when processing untrusted inputs. The solution is particularly beneficial for developers integrating third-party data, QA teams preparing test fixtures, and data engineers migrating configurations between systems. A key differentiator is deterministic output: key order can be preserved when requested, and formatting can be customized to match project conventions. Use cases include cleaning API payloads, preparing test fixtures, migrating config files, and ensuring consistent data interchange across services.
The tool adheres to RFC 8259 JSON standards for output and provides clear error reporting when inputs are structurally unsound, such as mismatched braces or unterminated strings. It supports common quirks like mixed quoting and single-quoted keys in a tolerant mode, but does not validate application-level semantics.
Overall, it reduces manual editing, minimizes syntax errors, and accelerates data workflows by delivering reliable, ready-to-use JSON.
