Frequently Asked Questions (FAQ)

Q. Is my JSON data stored or transmitted?

A. No, all calculations and formatting take place directly in your browser. No data is sent to external servers, making it safe for processing private information.

Q. What does the validation error line mean?

A. It indicates the exact line in your document where the syntax error began (e.g., missing commas, open brackets, or wrong quotes). Reviewing the surrounding lines will help you fix the structure.
