I downloaded an export from an app and it is a .json file. When I open it in Notepad everything is on one long line. How do I read it?

JSON is a plain text format for structured data, so any text editor opens it. The long line is just minified JSON. To make it readable:

• Browser: Chrome and Edge can open a JSON file (drag it into a tab). Firefox has a built in JSON viewer with collapsible sections and a Pretty Print option.
• VS Code: open the file and press Shift + Alt + F to format it.
• Excel: Data > Get Data > From File > From JSON, which turns arrays of records into a table.
• Notepad++ with the JSON Viewer plugin does the same.

Be careful with very large JSON files. Notepad can freeze, so use VS Code or a tool made for large files.

Firefox's viewer is exactly what I needed. Thanks.
