String to JSON Parser

JSON often arrives wrapped in extra layers of escaping — from log files, database fields, API responses that double-encode payloads, or message queues. This tool peels back those layers and gives you the clean, parsed JSON you actually want to read or process.

When do you need this?

Anytime you see backslashes before quotes (\"), literal \n in strings, or JSON wrapped in extra quotes. Common sources: CloudWatch logs, Splunk events, Postgres jsonb columns stored as text, webhook payloads that JSON.stringify'd their body, or LLM responses returning JSON inside a string.

How our parser handles escape layers

We first try a direct JSON.parse. If that fails and the input is wrapped in quotes, we parse it as a string then re-parse the result — handling double-escaping. We also normalize common escape sequences (\n, \r, \t, \", \\) before a final parse attempt.

Edge cases we handle

Strings with embedded newlines, tab characters, Unicode escapes, mixed quoting, and arbitrarily-nested escape layers. If parsing fails at every layer, you get a clear error message pointing to the issue.

Common input formats supported

• Single-escaped: {"key":"value with \"quotes\""}
• Double-escaped: "{\"key\":\"value\"}"
• Triple-escaped (rare): "\"{\\\"key\\\":\\\"value\\\"}\""
• Logs with literal \n, \t, \r sequences
• API responses with stringified body fields
• Database TEXT columns containing JSON

Whether you're debugging a production log line, extracting JSON from a webhook payload, or inspecting an LLM response, this parser saves you from manually counting backslashes.
