How to Use
What is the Document Converter?
The document converter handles text and Office document conversions in five tabs. Everything runs in your browser.
Markdown ↔ HTML
- Markdown to HTML uses the marked library with GFM support. Raw HTML in your Markdown is escaped and displayed as text for safety.
- HTML to Markdown uses the mature Turndown library to produce clean Markdown.
CSV ↔ JSON
- Supports comma, semicolon and tab delimiters.
- The first row can be used as the header (object keys).
- Quoted fields with commas and line breaks are handled correctly.
XML ↔ JSON
- Convert XML to JSON (attributes become @_ keys, repeated tags become arrays).
- Convert JSON back to XML with support for attributes.
- Pretty-print or minify XML with error location hints.
Office Import
- DOCX files can be converted to HTML or Markdown.
- XLSX files can be converted to JSON or CSV, with sheet selection.
Office Export
- Write Markdown documents as .docx files (headings, lists, tables, bold, italic).
- Write JSON or CSV data as .xlsx spreadsheets.
Tips
- Use the Load example button to see a sample for each mode.
- Copy or download the result with the buttons above the output area.
