About Our Text File Converter
Our Text Format Converter is a powerful, free online tool designed to help developers, writers, and data professionals convert between various text and data formats quickly and accurately. Whether you're working with documentation, APIs, data files, or web content, this tool makes format conversion effortless.
Supported Conversions
Markdown to HTML
Convert Markdown syntax to clean, semantic HTML. Perfect for documentation, README files, blog posts, and static site generators. Our converter supports standard Markdown syntax including headers, lists, links, images, code blocks, and more.
HTML to Plain Text
Extract plain text content from HTML documents by removing all tags and formatting. Useful for content analysis, text extraction, and creating text-only versions of web content.
JSON Formatting
Beautify (format) or minify JSON data. The beautify option adds proper indentation and line breaks for readability, while minify removes all unnecessary whitespace to reduce file size. Includes validation to catch syntax errors.
CSV to JSON & JSON to CSV
Convert between CSV (Comma-Separated Values) and JSON formats. CSV to JSON converts tabular data into structured JSON arrays, while JSON to CSV creates spreadsheet-compatible files from JSON data. Essential for data import/export operations.
XML to JSON
Transform XML documents into JSON format for easier processing in modern applications. Preserves the structure and attributes of XML elements while converting to a more JavaScript-friendly format.
YAML to JSON & JSON to YAML
Convert between YAML (YAML Ain't Markup Language) and JSON. YAML is commonly used for configuration files, while JSON is the standard for web APIs. Our converter handles both directions seamlessly.

Frequently Asked Questions
What formats can I convert between?
Our tool supports Plain Text, Markdown, HTML, JSON, XML, CSV, and YAML. Not all format combinations are supported - for example, you can't directly convert CSV to XML. The tool will show an error if a conversion isn't available.
How do I use the live preview feature?
When converting to HTML or Markdown, you'll see an eye icon in the output panel. Click it to toggle between viewing the raw code and the rendered preview. This lets you see exactly how your content will look when displayed.
What's the difference between beautify and minify for JSON?
Beautify adds proper indentation and line breaks to make JSON more readable for humans. Minify removes all unnecessary whitespace to make the file smaller, which is useful for production environments where file size matters.
Can I convert large files?
Yes, but very large files (over 1MB) may slow down your browser since all processing happens client-side. For best performance, we recommend breaking very large files into smaller chunks or using command-line tools for bulk processing.
Is my data safe? Do you store my text?
Absolutely safe! All conversions happen entirely in your browser using JavaScript. Your text never leaves your device or gets sent to any server. This ensures complete privacy and works even offline once the page is loaded.
Why does my XML/JSON conversion fail?
The most common reason is invalid syntax in your input. Make sure your XML is well-formed (all tags are properly closed) and your JSON has valid syntax (proper quotes, commas, and brackets). The error message will help identify the issue.
