How this service works
Converts JSONL rows to JSONL, chat training examples or Markdown. Returns the serialized result as an output string with stats. No AI.
Output
A serialized string containing the reformatted content (JSONL rows, chat-format messages, or Markdown) along with statistics about the transformation such as row counts and any conversion metrics. No AI-generated content is added.
Example use cases
Fine-tuning dataset preparation
“I have a JSONL file of question-answer pairs I need to convert to OpenAI chat format for fine-tuning. Can you reformat it with the system prompt 'You are a concise assistant who answers factual questions'?”
Dataset documentation as Markdown
“Convert my JSONL dataset rows into Markdown so I can paste them into a README or documentation page — just the plain formatted output, no AI rewriting.”
Clean JSONL passthrough with stats
“Reformat this JSONL input back to JSONL layout and tell me the stats — I want to keep the _quality score fields in the output this time.”
Technical details
Endpoint
POSThttps://route-a-worker.frostskynet-api.workers.dev/format?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, rule-based conversion of JSONL data into chat training examples or Markdown without any AI rewriting or inference. It is ideal for ML data pipeline steps where reproducibility and speed matter, and when you want an option to retain or strip _quality score fields produced by the sibling scoring endpoint.
Side effects
- Empty input string rejected (minLength:1 enforced)
- Request body exceeds size limit — the entire UTF-8 JSON body including options counts toward the limit
- Invalid format enum value causes validation error
- System prompt exceeds 2000 character maximum
- Malformed JSONL input that cannot be parsed
