Frequently Asked Questions
Questions about the JSON Viewer? We've got answers.
What is the maximum JSON size the viewer can handle?
The JSON Viewer processes data entirely in your browser. Files up to several megabytes work well. Extremely large files may cause slower rendering due to the recursive tree generation.
How does the search feature work?
Search scans both keys and string values in the JSON tree. Matching nodes are highlighted instantly, and the match count is displayed. Only expanded nodes are searchable.
Is my JSON data sent to any server?
No. All processing happens locally in your browser. Your data never leaves your device.
