Frequently Asked Questions
How are field names formed?
Keys are converted to exported Go names in CamelCase, while the original key is preserved in a json struct tag.
How are types mapped?
Whole numbers become int, decimals become float64, true or false becomes bool, and text becomes string.
What about nested objects?
Each nested object becomes its own struct, referenced from the parent field.
Is my data sent anywhere?
No. The generation runs entirely in your browser, so your JSON never leaves the tab.
Is it free?
Yes. Every tool here is free to use with no sign up.
