JSON Copilot

How do I open and read a JSON file?

Usage & Getting Started

A .json file is a plain-text file, so you can open it in any text editor, a web browser, or a code editor. To actually read it comfortably, the easiest way is to paste its contents into a JSON viewer that formats and color-codes the structure for you.

Ways to open a JSON file

  • JSON Copilot: paste the file's contents and instantly format it or open the tree view for collapsible navigation. Nothing is uploaded; it stays in your browser.
  • Web browser: drag the file into Chrome, Firefox, or Edge. Firefox even shows a built-in tree view.
  • Code editors: VS Code and similar editors add syntax highlighting and validation.
  • Text editors: Notepad, TextEdit, or any editor opens it as raw text (no formatting).

Read a JSON file in 3 steps

  1. Open the file in any text editor and copy everything
  2. Paste it into the JSON Copilot editor
  3. Click Format to beautify it, or switch to Tree / Mind Map to explore the structure

If the file won't parse, it may contain a syntax error. See how to fix JSON validation errors. Working with a big export? See large JSON files.
