About JSON and XML

JSON

JavaScript Object Notation is an open standard file format widely used for data storage and interchange. Language independent with built-in support in many programming languages like Python. Douglas Crockford specified the JSON format in the early 2000s.

JSON combines readability with structured format, making it ideal for data transfer and storage. Many databases including MySQL and PostgreSQL support JSON storage and querying.

XML

Extensible Markup Language is a markup language where HTML is a subset of XML. Originally the most widespread format for data interchange and heavily used by SOAP APIs. It allows for the structuring of documents that can be programmatically validated.

Although JSON has replaced XML in many use cases, XML continues to be widely used in enterprise systems, configuration files, and document-based applications.

Coming Soon

We're working on advanced features including PDF to XML conversion for data entry automation, batch processing capabilities, and API access for programmatic validation. Stay tuned for these exciting updates!
