How this service works
Turns a document into clean Markdown in about a second: pass an https URL or base64 of a PDF, Word, Excel, PowerPoint, HTML, CSV or XML file and get the text back with its headings, tables and page markers, plus the token count. It reads the text layer, so a scanned page with no text layer comes back without text. You are only charged if the Markdown is delivered. No API key, no account.
Output
Returns clean Markdown with the document's headings, tables, and page markers preserved, along with the token count of the extracted text. Scanned documents without a text layer will return without readable text.
Example use cases
Extract contract text for AI review
“I have a contract PDF at https://contracts.example.com/agreement.pdf — can you pull out all the text as Markdown so I can feed it into my AI for analysis?”
Parse Excel spreadsheet as markdown table
“Convert this base64-encoded Excel file into Markdown for me so I can see all the tables and data in a readable format — here's the base64: [base64string], filename is report.xlsx.”
Turn PowerPoint slides into readable notes
“I've got a PowerPoint presentation at https://files.example.com/slides.pptx — convert it to Markdown so I can read through the slide content as structured text.”
