JSON Viewer
Explore JSON as a tree you can fold and search.
Questions
How large a file can it show?
Files of tens of megabytes open: only the branches you unfold are drawn, and long arrays are shown in pages of 200 items.
What is the path shown for each value?
A JSONPath expression such as $.orders[3].customer.name. Tools like jq, Postman and many programming libraries accept this notation to pick out the same value.
Are big numbers shown correctly?
Yes. Values are shown exactly as written in the file, so IDs longer than 16 digits aren’t rounded the way JavaScript would round them.
Can I format or minify the JSON?
Use the JSON Formatter, which formats, minifies and validates, with errors by line and column.
Is my JSON uploaded anywhere?
No. Your JSON is opened and processed on your device, and the results are saved straight back to it. Nothing is uploaded. How to check.
Is it free? Do I need an account?
It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
