About JSON Reader
Not everyone who receives a JSON file is a developer. Maybe it is an export from an app, a settings file, or a data dump someone sent you. Double clicking it often opens a wall of text. Drop the file here instead and read it like a folder structure.
The file is read locally by your browser. We never see it.
Frequently asked questions
Can I open a file from my phone?
Yes. The page works on phones and tablets. On small screens the input and output stack vertically.
What file types can I open?
.json and .txt files with JSON content work best. Any text file will load, and if it is not valid JSON you will be told where it goes wrong.
Why can I not open an Excel or PDF file here?
This tool reads JSON text. For Excel files, try the Excel to JSON converter, which turns a spreadsheet into JSON you can then read here.
Is there a size limit?
There is a generous limit, and several megabytes work without trouble. If a file is too large you get a clear message with the limit.
