Frequently Asked Questions
Instant answers to common questions regarding security, performance, and usage.
Is it fundamentally safe to paste production-sensitive JSON into this web formatter?
Absolutely. Our engine is purely client-side. The data you paste into the forge exists strictly within your computer's local memory. We literally have zero server-side logic capable of reading, storing, or inspecting your sensitive application keys or customer data packets.
Does the tool actively automatically detect and fix common JSON syntax errors?
While we do not recommend automated fixing (which can unintentionally alter logic), our industrial-grade validator pinpoint precisely indicates the exact character and line number that violates the JSON specification, allowing you to manually fix objects with total control.
What is the primary difference between 'Prettify' and 'Beautify' within this tool?
These are synonymous industrial terms. Our engine expands compressed, minified data into a standardized, indented (2-space) hierarchical structure that is perfectly optimized for human readability and structural auditing.
