Test it

Using "json-validator". Validate a payload containing a trailing comma after its final property.

Expected outcome:

Validation failed on the affected line. Remove the final comma, then validate the corrected payload.

Using "json-validator". Analyze a customer export with records, contact fields, and optional metadata.

Expected outcome:

  • Top-level type: array
  • Each item is a customer object
  • Metadata is optional and nested
  • Contact fields use inconsistent value types

Using "json-validator". Convert a flat JSON user list to YAML.

Expected outcome:

A YAML user sequence is returned with identifiers and names preserved in their original types.

What You Can Build

Repair API Payloads

Locate syntax errors in request or response bodies and receive corrected JSON with concise explanations.

Clean Configuration Files

Validate and format configuration data before deployment or version control review.

Inspect Data Structures

Summarize unfamiliar JSON datasets and identify inconsistent fields, types, or nesting.

Try These Prompts

Check JSON Syntax 
Validate this JSON. List each error with its line number and explain the required correction: {{json_data}}
Format Valid JSON 
Validate and format this JSON with two-space indentation. Preserve key order and all value types: {{json_data}}
Repair and Explain 
Repair this JSON. Show a concise issue list, explain every change, and ask before altering valid structure: {{json_data}}
Analyze and Convert 
Analyze this JSON structure, report types and nesting, then convert it to {{target_format}}. Explain any flattening decisions: {{json_data}}

Best Practices

  • Provide complete input so error locations and nesting can be assessed accurately.
  • Validate before formatting or converting the data.
  • Confirm optional changes such as key sorting, comment removal, or nested-data flattening.

Avoid

  • Do not treat repaired output as schema-compliant without a separate schema check.
  • Do not flatten nested data without defining how arrays and objects should map.
  • Do not replace the original file until the corrected output has been reviewed.

Frequently Asked Questions

Can this skill fix invalid JSON?
Yes. It identifies common syntax errors and proposes corrected content with explanations.
Does it validate against JSON Schema?
No. It focuses on JSON syntax, formatting, repair, conversion, and structural analysis.
Can it preserve key order?
Yes. Key sorting is optional and should occur only after user confirmation.
Which formats can it produce?
It provides guidance for converting JSON to YAML, TOML, CSV, and XML.
How are nested arrays handled during CSV conversion?
The structure may need flattening. The user should define the desired row and column mapping.
Does formatting change data types?
It should preserve strings, numbers, booleans, null values, objects, and arrays.
