Document & Web Converters
Convert Markdown, HTML, JSON, XML, and plain text into the documents and data formats you actually need to hand over — free and in the browser.
These are the developer-adjacent conversions: a README that has to become a PDF for a submission, an API response that needs to land in a spreadsheet, an HTML invoice that must be a fixed document, a config file that arrived as XML when your tooling wants JSON. All of it is the same underlying problem — the content is right and the container is wrong.
Conversions parse the source properly rather than pattern-matching text, so Markdown tables and code blocks render as tables and code blocks, and nested JSON is flattened to columns in a predictable way.

Which document tool do you need?
Match the source you have to the output someone is asking for:
| What you need to do | Use this tool |
|---|---|
| A README or notes must be submitted as a PDF | Markdown to PDF |
| I need Markdown rendered as web-ready HTML | Markdown to HTML |
| A web page or invoice needs to be a fixed document | HTML to PDF |
| HTML content needs to be editable in Word | HTML to Word |
| Plain text needs to become a proper PDF | Text to PDF |
| I need to hand JSON to someone as a document | JSON to PDF |
| API data needs to open in a spreadsheet | JSON to CSV |
| Legacy XML needs to become usable JSON | XML to JSON |
Why Markdown and HTML need converting at all
Markdown is written to be readable as plain text and rendered later, which makes it excellent for documentation and useless as a deliverable. Nobody accepts a .md file as an assignment, a report, or a client hand-off. Converting to PDF applies real typography — headings, spacing, monospaced code blocks, working tables — and produces something that opens identically everywhere.
HTML has the opposite problem: it renders everywhere but is not fixed anywhere. The same invoice or certificate reflows by viewport, and a browser's own print dialogue adds headers, footers, and page numbers you did not ask for. Converting to PDF pins the layout and drops the browser chrome, which is why it is the standard step for generated invoices, receipts, and certificates.
JSON to CSV is the same mismatch in data form. JSON is hierarchical and nests arbitrarily; a spreadsheet is a flat grid. The conversion walks the structure and flattens nested keys into columns, so an API response becomes something a non-technical colleague can open in Excel or Sheets without touching a parser.
Document and web tools FAQ
Are Markdown tables, code blocks, and links preserved?
Yes. Standard Markdown plus common GitHub-flavoured extensions are parsed, so tables render as tables, fenced code keeps its monospaced formatting, and links stay clickable in the PDF.
Does HTML to PDF include the CSS styling?
Yes. The page is rendered with its stylesheet applied, so layout, fonts, and colours match what a browser shows — without the print headers and footers a browser adds.
How is nested JSON handled when converting to CSV?
Nested objects are flattened into dot-notation column headers and arrays are expanded into rows, giving a predictable flat table rather than raw JSON dumped into one cell.
Can I paste content instead of uploading a file?
Yes. The text-based tools accept pasted Markdown, HTML, JSON, or XML directly, which is usually faster than saving a file first.
Is my code or data sent anywhere else?
No. Content is used only to produce your output and is deleted once processing finishes. Nothing is logged, stored, or used for training.
