About this tool
Data Formatter is a free online tool. Format and validate YAML and XML, and convert between them and JSON — all in your browser.
Enter data (such as JSON) and select the target format (such as YAML, CSV, SQL INSERT statements, etc.). The tool parses the source format and converts it to the target format for output. Supports formatting (beautification) and compression (removal of white space). It verifies the data syntax and prompts the specific location when an error is found.
The conversion uses parsers and generators in each format: native JSON.parse/stringify for JSON, js-yaml for YAML, xml2js for XML, and PapaParse for CSV. SQL generation creates CREATE TABLE and INSERT statements based on the data structure.
It is suitable for migrating data between different systems, such as converting JSON returned by an API into SQL for import into a database, or converting CSV into JSON for front-end use. It is also used to debug data format issues.
Data format conversion tool converts data between JSON, XML, YAML, CSV, SQL and other formats, and supports formatting and verification.
