Extract JSON from Markdown FAQ
How does JSON extraction from markdown work?
The tool scans your input for markdown code blocks (```json, ```, etc.), extracts the content inside, attempts to parse it as JSON, and presents the formatted result. If multiple JSON blocks are found, it extracts all of them.
Does it work with mixed markdown and JSON?
Yes. You can paste an entire ChatGPT or Claude response with explanations, headings, and code blocks. The tool finds and extracts only the JSON content.
What if there are multiple JSON blocks?
The tool extracts all JSON blocks and presents them as a JSON array. You can also choose to extract only the first block if preferred.
Will it validate the extracted JSON?
Yes. After extraction, the JSON is parsed and validated. If there are syntax errors, you'll see a clear error message with the issue.
Is my data sent to a server?
No. All extraction and validation happens locally in your browser. Your data never leaves your computer.
