Turn messy code, JSON, HTML or CSV into clean, hierarchical Markdown — and cut your prompt down to size.

How it works
Paste source code, JSON, HTML or CSV. The converter detects the format and rebuilds it as clean, hierarchical Markdown — collapsing redundant whitespace, dropping boilerplate and minifying structure. Everything runs in your browser, and the result can shrink a prompt by up to 60%.
Why convert to Markdown for LLMs?
LLMs read Markdown far more reliably than raw HTML or minified JSON, and they charge by the token. Boilerplate — closing tags, indentation, repeated keys, comments — inflates a prompt without adding meaning the model needs. Converting to clean, hierarchical Markdown locally can cut a prompt by half or more, so you fit more context in the window and pay less per call.
FAQ
- Is my input sent anywhere?
- No. Format detection and conversion run 100% in your browser — your source code or data never leaves your device. The page only sends an anonymous usage counter (the tool name and the input size), never the content.
- How does it save tokens?
- It removes whitespace, comments and markup boilerplate that cost tokens without adding meaning, and restructures content into compact Markdown that an LLM parses efficiently.
- Which formats can it convert?
- JSON, HTML, CSV and raw source code. The format is auto-detected; HTML is parsed with the browser native engine and reduced to semantic Markdown.
- Is there a size limit?
- Only your device memory. With no server there is no upload cap; large files convert locally in a fraction of a second.
