Format and Copy JSON Directly in the Browser Console

2024-06-21

When the object is already in memory, a one-liner in Console beats exporting HAR files—if you know how to copy valid JSON text.

copy and stringify

Chrome copy(obj); universal: copy(JSON.stringify(obj, null, 2)).

copy(JSON.stringify(responseData, null, 2));

console.table

Good for object arrays; deep nesting still needs stringify or formatted output from an online tool.

Network panel

Copy response; huge bodies may truncate—use curl/file for giants.

Circular refs

DOM-linked objects fail stringify—copy plain subsets only.

With online tools

Console → paste local formatter → validate, minify, save fixtures securely.
