How do I edit JSON online?

Paste your JSON data into the input area or drag and drop a .json file. The data is instantly displayed as an editable table. Double-click any cell to modify its value, then click Download JSON to save the edited file. All processing happens in your browser.

Can I view JSON as a table?

Yes. JSONXX automatically converts JSON arrays into a table view. Nested objects are flattened using dot notation (e.g., user.address.city). You can sort columns, hide columns, and resize the table to fit your data.

Can I edit nested JSON objects?

Yes. Nested JSON objects are flattened into columns using dot notation. You can edit any cell in the table, and when you export back to JSON, the data is reconstructed with the original nested structure preserved.

Can I add or delete rows in the JSON editor?

Yes. Right-click any row to insert a new row above or below, or delete the row. You can also use undo (Ctrl+Z) and redo (Ctrl+Y) to manage changes.

Is my JSON data safe in this editor?

Yes. All processing happens 100% in your browser. Your JSON data is never uploaded to or stored on any server. No backend, no tracking.

JSON Editor — Best Practices

Validate Before Editing

Use the validate button after each change to catch syntax errors early. Real-time validation markers show issues as you type.

Use Tree View

The tree view helps navigate large JSON files. Collapse/expand sections to focus on specific parts of your data structure.

Search & Replace

Use the search feature to find specific keys or values. The replace function helps batch-update values across the entire structure.

Export Formats

Choose between beautified (readable) and minified (compact) JSON output. Both formats are fully valid and ready for use in your projects.

JSON Editor — FAQ & Troubleshooting

How do I use the JSON Editor?

Paste your JSON data or upload a .json file. The editor provides syntax highlighting, tree navigation, and real-time validation. Edit directly in the code view or use the tree view to navigate large structures. Export beautified or minified JSON as needed.

Does the editor support JSON validation?

Yes. Real-time validation shows syntax errors with line numbers and descriptions. The editor highlights invalid regions as you type, helping you catch and fix issues immediately. It also supports JSON with comments (JSONC) for development use.

Can I search and replace within the JSON?

Yes. The search feature finds keys and values across the entire structure. The replace function supports single or batch replacement, with optional regex mode for advanced patterns.

What is the difference between tree view and code view?

Tree view displays the JSON as a collapsible tree, ideal for browsing large structures and understanding hierarchy. Code view provides direct text editing with syntax highlighting, better for making precise changes and bulk edits.

Can I format or minify my JSON?

Yes. Use the Beautify button for properly indented, readable output. Use the Minify button for compact production-ready JSON with all whitespace removed. Both options produce valid JSON.

Is my data safe when using the online editor?

Absolutely. All processing happens entirely in your browser. Your JSON data is never sent to any server, stored, or tracked. This is especially important when editing sensitive configuration data or API responses.
