As JSON

Interpret note content as JSON, automatically stripping surrounding text, code fences, and other noise. Optionally extract specific fields.

Purpose

• Extract JSON from LLM responses with preambles or explanations
• Strip markdown code fences (json ... )
• Handle mixed content with embedded JSON
• Extract specific field values
• Validate JSON structure

Input Format

Accepts a Note containing JSON (clean or embedded):

• Clean JSON: {"key": "value"}
• Code fenced: ```json\n{"key": "value"}\n```
• With preamble: Here's the data:\n{"key": "value"}
• With trailing text: {"key": "value"}\nAs you can see...

Parameters

Optional:

• field - Field name to extract (searches recursively, e.g., "url", "title", "email")
• all - If true, returns all matching fields, one per line; if false/omitted, returns first match (default: false)

Output Format

• No field: Full parsed JSON as formatted text
• With field (all=false): First matching field value as text
• With field (all=true): all matching field values, one per line
• Field not found: note-null
• JSON not identified: FAIL (hard error)

Usage Examples

Extract JSON from LLM response: {"type":"as-json","target":"$llm_response","out":"$parsed"}

Extract first matching field: {"type":"as-json","target":"$response","args":{"field":"title"},"out":"$title"}

Extract all matching fields: {"type":"as-json","target":"$response","args":{"field":"url","all":true},"out":"$all_urls"}

Guidelines

• Strips leading/trailing text and code fences automatically
• Field search is recursive - finds field at any depth
• Field not found returns note-null (soft failure, plan continues)
• No valid JSON found triggers FAIL (hard failure, plan should handle)
• Preserves data types in extracted values
• Default extracts first match; use all: true for all matches

Examples

Extract first match: Input: {"results": [{"url": "https://example.com/1"}, {"url": "https://example.com/2"}]}
field: "url"
Output: https://example.com/1

Extract all matches: Input: {"results": [{"url": "https://example.com/1"}, {"url": "https://example.com/2"}]}
field: "url", all: true
Output: https://example.com/1\nhttps://example.com/2

Strip code fence: Input: Here's the data:\n\``json\n{"count": 42}\n``` field: "count" Output:42`

Missing field: Input: {"name": "Alice"}
field: "email"
Output: note-null

Output ONLY the selected information as shown above, no introductory, explanatory, reasoning, code fences, etc.
