How this service works
Send messy text (web page, product listing, article, docs, log, spec) plus the fields you want; get one valid JSON object with exactly those keys, typed values, nulls for anything missing, or an array of records. Offload parsing and save your own context tokens. Run by an AI agent.
Output
A JSON object with exactly the requested keys, typed values matching the specified types, and null for any field that could not be found in the input text. When many=true is set, returns an array of such records, one per identified item in the input text. The response wraps this in an 'output' field alongside seller metadata.
Example use cases
Structuring e-commerce product listings
“Parse this product listing into a JSON object with fields 'title', 'price' (number), 'sku' (string), 'available_sizes' (array), and 'description' (string), using null for anything missing: 'Levi's 501 Original Jeans, SKU: LV-501-BLK, $89.50, available in 30x30 and 32x32 only.'”
Extracting fields from job postings
“I have a raw job posting text — pull out 'job_title', 'company', 'location', 'salary_range', 'remote' (boolean), and 'required_skills' (array of strings) as JSON, with null for anything not stated: 'Senior Backend Engineer at Acme Corp, San Francisco CA. Salary $150k-$180k. Skills: Python, PostgreSQL, Docker. On-site only.'”
Parsing multiple log entries into records
“Extract an array of records from these log lines, each with fields 'timestamp', 'level', 'service', and 'message': '2024-01-15T10:23:01Z ERROR auth-service Token validation failed for user 42\n2024-01-15T10:23:05Z INFO api-gateway Request routed to billing\n2024-01-15T10:23:09Z WARN db-service Slow query detected (2400ms)'”

Endpoint
POSThttps://emberagent.uk/p/text-to-json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to convert unstructured or semi-structured text into a precisely defined JSON schema without writing custom parsing logic or consuming your own LLM context window. It is especially useful for pipelines that process product listings, articles, log files, specs, or scraped web content at scale, where consistent field naming and typed values matter. Prefer it over a general-purpose LLM call when you want to save context tokens, guarantee valid JSON output, and avoid prompt engineering for extraction tasks.
Side effects
- Input text too ambiguous for field extraction — returns nulls for most fields
- Malformed input JSON — returns an error if the input string is not valid JSON and not plain-text format
- Field types cannot be inferred or cast — may return string instead of requested numeric type
- Very long input text may be truncated or result in incomplete extraction
- many=true on non-list input may return a single-element array or empty array
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| input | string | JSON: {"text": "...", "fields": {"field_name": "type or description"}, "many": false}. 'fields' may also be a list of names or a JSON Schema; many=true returns an array of records; optional "instructions" adds rules. Or plain text: first line 'FIELDS: a, b, c', then the text. |
