Frequently Asked Questions

EVERYTHING YOU NEED TO KNOW ABOUT OUR FORMATTERS

What formats does FormatData support?

FormatData currently supports JSON, XML, HTML, and JavaScript formatting with plans to add more formats in the future. Each formatter offers specialized features for its respective format, including validation, prettifying, and syntax highlighting.

Is FormatData free to use?

Yes, all of our formatting tools are completely free to use with no limitations. There's no registration required, and your data never leaves your browser - all formatting is done client-side for maximum privacy and security.

How does the JSON formatter handle large files?

Our JSON formatter is optimized to handle files up to 50MB in size with efficient memory usage. For larger files, we recommend using our minification option first to reduce file size before attempting to format.

Can I customize the indentation and formatting options?

Absolutely! Each formatter provides customization options such as indent size (2, 4, 6, or 8 spaces), line wrapping options, and format-specific settings like minification for JSON or collapsing content for XML.

Is my data secure when using FormatData?

Your security is our priority. All formatting operations happen entirely in your browser - your data is never sent to our servers or stored anywhere. This ensures complete privacy and security for sensitive information.

Can I use keyboard shortcuts with the formatters?

Yes, all our formatters support keyboard shortcuts for common operations. Press Ctrl+Enter (or Cmd+Enter on Mac) to format, Ctrl+S to download the formatted output, and Ctrl+C to copy the formatted code to your clipboard.
