Workflow guide
XML tools help users format, validate and convert Extensible Markup Language data. XML is still used in enterprise systems, legacy integrations, SOAP APIs, feeds, configuration files and document exchange workflows. FormatForge XML tools help users beautify XML, check syntax and convert XML into JSON or JSON into XML.
Readable XML is easier to debug and maintain. A formatter adds indentation and line breaks, while a validator helps catch missing closing tags, broken nesting and invalid syntax. XML to JSON conversion helps developers bring legacy data into modern application workflows. JSON to XML conversion is useful when a system still expects XML input.
A common XML workflow starts with formatting messy XML, validating the syntax and then converting it to JSON for easier processing. Enterprise users may convert JSON back to XML for legacy imports. Developers working with APIs, feeds and integration files often need both XML and JSON tools together.
Use XML tools when working with feeds, SOAP integrations, legacy exports or configuration files. If your XML requires XSD validation, you may need advanced schema validation. For basic syntax and conversion work, browser-based tools are often sufficient.
