How do I import and export JSON files?
Usage & Getting Started
By Dmitrii Kargashin · Updated October 2025
JSON Copilot imports and exports JSON files in a few ways: load files from your computer, paste from the clipboard, or export your results.
Import Methods
Paste from Clipboard
Paste JSON directly into the editor using Cmd/Ctrl + V. This is the quickest way to start.
Import from File
Click the "Import" button in the toolbar to open a file picker, then select a .json file. JSON Copilot loads and validates the contents.
Export Methods
Copy to Clipboard
Click the "Copy" button or press Cmd/Ctrl + K
Perfect for pasting into code editors, emails, or documents.
Download as File
Click the "Export" button to download your JSON as a .json file
Saves to your Downloads folder with automatic file naming.
Automatic Validation
Instant Validation on Import
When you import or paste JSON, JSON Copilot automatically validates the syntax. Invalid JSON triggers clear error messages with line numbers to help you fix issues quickly.
Supported File Types
.json
Standard JSON files
.jsonc
JSON with comments
.txt
Plain text with JSON
Privacy Note
File imports and exports happen entirely in your browser. These operations do not send data to any server.
Pro Tip
You can import files one after another. JSON Copilot replaces the current content each time. To work with multiple JSON files at once, use browser tabs to keep several instances open.
