Short answer

How can I use my AI to validate JSON?

Your agent uses the validate_json_document tool to compare your JSON data against a target schema. It identifies missing keys, incorrect data types, and structural flaws. You get a clear report of exactly where the file fails the definition.

The results.

Where every error lands.

The AI processes the raw data and outputs specific results based on the schema provided.

ERROR

Structural failures

The AI flags missing required fields or incorrect nesting. You see exactly which parts of the document break the rules.

TYPE

Data type mismatches

The agent catches when a string is sent instead of an integer or a boolean. This ensures your downstream systems don't crash.

VALID

Clean pass confirmation

If the document matches the schema perfectly, the AI confirms the file is safe to use. You get a green light for your pipeline.

HUMAN

Manual fixes

The AI points out the errors, but you decide how to rewrite the source data. You maintain full control over the final file.

The workflow

What your AI does when the JSON arrives.

The agent acts as a gatekeeper between your raw data and your application requirements.

  1. Ingest data

    Your agent reads the JSON content and the schema you want to enforce.

    validate_json_document

  2. Run comparison

    The agent executes a deep check of every key and value against the schema rules.

    validate_json_document

  3. Identify violations

    The AI isolates specific paths in the JSON where the structure or type is wrong.

    validate_json_document

  4. Report findings

    The agent presents a readable summary of the errors or a confirmation of validity.

FAQ

How this task behaves.

  • 01

    Can the AI fix the JSON errors automatically?

    No. The AI identifies the errors and tells you where they are, but you must perform the actual edits to your files.

  • 02

    Does the AI change my original JSON files?

    No. The tool only reads and validates the data. It does not write or overwrite your files.

  • 03

    Can I validate multiple files at once?

    Yes, you can ask your agent to loop through a list of files or a specific directory for validation.

  • 04

    What happens if the schema is also invalid?

    The validation process requires a valid schema to function. You should ensure your schema is correct before running the check.

  • 05

    Can the AI check for custom logic beyond the schema?

    The tool specifically validates against the provided schema. If you need to check business logic that isn't in the schema, you'll need to ask your agent to do that separately.
