How to use the JSON Visual Editor Online

Edit nested JSON as a tree or a table and export it again.

The JSON Table Editor lets you edit nested JSON without writing code. Open it as a tree to change any value, add or delete keys and items, and change types. Or switch to the Table view, where a list of objects becomes rows and columns (nested fields become columns such as customer.name), and edit cells like a spreadsheet. Every edit updates the JSON, so you can download it again as JSON, or export the table as CSV, Excel or Parquet. You can also open a CSV or Excel file and turn it into JSON; columns named like a.b become nested objects. It all runs in your browser.

  1. Drop or paste JSON
  2. Edit in the Tree, Table or Text view
  3. Download the JSON or the table

Frequently asked questions

Is there a visual JSON editor online?

Yes. Paste or drop JSON and edit it as a tree. Nothing is uploaded.

Does it handle nested JSON?

Yes. The Tree view shows every level. The Table view flattens nested fields into columns, and your edits go back into the nested JSON.

Can I turn a table back into JSON?

Yes. Open a CSV or Excel file, edit it, and download the JSON. Column names with dots, such as customer.name, become nested objects.
