Understanding Data Formats

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that's easy for humans to read and write, and easy for machines to parse and generate. It's the most widely used data format for APIs and configuration files in web development.

Common uses: API responses, configuration files, data storage, web services communication.

What is YAML?

YAML (YAML Ain't Markup Language) is a human-friendly data serialization format. It uses indentation to represent structure and is more readable than JSON for complex configurations. YAML is popular in DevOps tools and configuration management.

Common uses: Docker Compose files, Kubernetes configurations, CI/CD pipelines, Ansible playbooks.

What is TOML?

TOML (Tom's Obvious, Minimal Language) is a configuration file format designed to be easy to read and write due to its simple and obvious semantics. It maps unambiguously to a hash table and is designed for configuration files.

Common uses: Rust Cargo.toml, Python Poetry configurations, application settings.

What is XML?

XML (eXtensible Markup Language) is a markup language that defines rules for encoding documents in a format that is both human-readable and machine-readable. XML is widely used for data interchange between systems and for configuration files.

Common uses: SOAP APIs, RSS feeds, configuration files, data interchange, document formats (SVG, DOCX).

How to Use This Tool

Format: Beautify and properly indent your JSON, YAML, TOML, or XML data for better readability.
Validate: Check if your data is syntactically correct and identify specific errors with line numbers.
Diff: Compare two data structures to find differences in values, added fields, or removed fields.
Convert: Seamlessly convert between JSON, YAML, TOML, and XML formats while preserving data structure.

Tips & Best Practices

Always validate your data before deploying to production environments
Use YAML for human-readable configurations, JSON for APIs, TOML for application settings, and XML for legacy systems
Be aware that TOML has limitations - it doesn't support nested arrays of tables as flexibly as JSON/YAML
XML uses a different structure (tags and attributes) compared to JSON/YAML's key-value pairs
When converting, some data types may be represented differently across formats
Use the diff tool to verify conversions maintain data integrity
Keep backups of your original data before converting formats
