Frequently Asked Questions
Does my JSON file upload to a remote database?
No. All file reads, parses, validation calculations, and formatting rules execute locally inside your local browser memory space. We do not transmit any input text to external endpoints.
What is JSON Tree View?
The Tree View converts standard plain-text JSON files into interactive node components. You can expand and collapse individual array items or nested objects to navigate large configuration structures easily.
Will invalid trailing commas work?
Standard JSON specifications do not permit trailing commas or single quotes. The parser will flag these characters as syntax errors and point to the line index containing the issue.
