How to parse unstructured text to JSON with your AI

Connect this MCP to your AI client once. From then on, your agent can pull specific patterns out of any text you give it.

Short answer

How do I turn messy text into structured JSON?

Your AI uses the extract_regex_matches tool to find specific patterns like email addresses or order numbers within a block of text. It then organizes those matches into a JSON array for you. You'll see how the extraction works below.

Data destinations

Where your data lands.

The AI processes the raw text and routes the results based on how you want to use them.

DATA

Structured JSON arrays

The AI uses regex to find matches and returns them as a clean JSON object. This makes the data ready for other scripts or databases.

LISTS

Cleaned data lists

Instead of a wall of text, you get a simple list of the specific items you asked for, like a list of all customer emails found.

LOGS

Formatted chat transcripts

The agent pulls timestamps or user IDs from chat logs and turns them into a structured format you can actually read.

REVIEW

Human verification needed

If a pattern is too messy or ambiguous, the AI flags it for you to check manually to ensure the JSON is accurate.

The workflow

What your AI does when text arrives.

The AI handles the heavy lifting of pattern matching so you don't have to write manual regex strings.

  1. Identify patterns

    Your agent looks at the raw text you provided and identifies the specific characters or sequences you want to isolate.

  2. Run extraction

    The AI executes the regex search to pull every instance of the target data from the unstructured block.

    extract_regex_matches

  3. Format output

    Once the matches are found, the agent wraps them in a JSON structure that follows your requested schema.

  4. Validate results

    The agent checks the extracted data against your requirements to ensure the JSON is valid and complete.

FAQ

How the parser behaves

  • 01

    Can the AI change the original text?

    No. The AI only reads the text to extract data; it does not modify your original files or messages.

  • 02

    Does the AI save my data?

    No. The AI processes the text in the moment to perform the extraction and does not store your unstructured text.

  • 03

    What happens if the regex doesn't find a match?

    The AI will return an empty list or a message stating that no matches were found for that specific pattern.

  • 04

    Can I use this to clean up messy spreadsheets?

    Yes, if you paste the text from the spreadsheet into your chat, the AI can extract the data into JSON.

  • 05

    Does the AI write the regex for me?

    Yes, you can describe the pattern you want in plain English, and the AI will handle the regex logic internally.
