How to Visualize JSON Data as a Table

Turn any JSON array into a sortable, interactive table — including nested objects.

What is the JSON to Table Tool?

The JSON to Table converter transforms JSON arrays and objects into a clean, interactive table — entirely in your browser. No data is uploaded anywhere. It handles nested objects and arrays automatically, sorting, column reordering, and hiding, making it especially useful for quickly inspecting API responses or exported datasets.

When Do You Need It?

Raw JSON is great for machines but hard to scan visually when you have dozens of records. The table view is the right choice when:

You receive an API response with an array of objects and want to compare values across rows
You need to quickly spot missing fields or unexpected nulls in a dataset
You are presenting data to a non-technical stakeholder who does not read JSON
You want to sort records by a specific field without writing code

Getting Started in 3 Steps

Open the JSON to Table tool.
Paste your JSON into the input panel on the left.
The table renders automatically on the right — no button to click.

Click Load Sample to see it working immediately with example data before pasting your own.

What JSON Structures Are Supported?

Array of objects (most common)

The ideal input is a JSON array where every element is an object with the same keys. This is the standard format returned by REST APIs.

[
  { "id": 1, "name": "Alice", "role": "admin", "active": true },
  { "id": 2, "name": "Bob",   "role": "editor", "active": false },
  { "id": 3, "name": "Carol", "role": "viewer", "active": true }
]

Each key becomes a column header, and each object becomes a row.

Nested objects

If a field's value is itself an object or array, the tool renders it as a sub-table inside the cell. No data is lost — the nesting is preserved visually.

[
  {
    "id": 1,
    "name": "Alice",
    "address": {
      "city": "New York",
      "country": "US"
    }
  }
]

The address column will expand to show city and country as nested rows.

Working with Columns

Sort by a column

Click the sort icon (↑↓) in any column header. Click once for ascending, again for descending, and a third time to remove the sort.

Hide a column

Click the × icon on a column header to remove it from view. This is useful when a field contains long blobs (like description or metadata) that obscure the columns you actually care about.

Reorder columns

Drag any column header left or right to change the column order. The table updates instantly. This is useful when you want related columns next to each other.

Maximize the table

Click the Maximize button (⤢) at the top right of the table panel to expand it to full page width — handy when you have many columns and need more horizontal space.

Real-World Use Cases

Inspecting API responses

Copy a JSON response from your browser's DevTools Network tab, paste it into the tool, and scan the table for unexpected values. You can sort by a timestamp column to see records in order, or hide the id and _links columns to focus on the business data.

Reviewing database export data

Many databases and ORMs can export query results as JSON. Pasting that export into the table view gives you a spreadsheet-like experience without needing Excel or a database GUI.

Comparing records side by side

Paste an array containing two or more records you want to compare. Sort by the field that differs most to identify patterns quickly.

Sharing with non-technical colleagues

The table layout is far more readable than raw JSON for anyone not familiar with the format. Take a screenshot of the table view or describe what you see using the sorted, column-filtered view.

Tips and Tricks

Mixed-key arrays: If some objects are missing a key that others have, the missing cells show as empty. This makes it easy to spot incomplete records.
Large datasets: The table renders all rows, so very large arrays (thousands of records) may be slow. For exploration, paste a representative sample first.
Dates and numbers: Sorting is alphanumeric, so ISO 8601 date strings ("2026-06-01") sort correctly. Non-ISO date formats may not sort as expected.
The input panel stays editable: You can tweak the JSON directly in the input panel and the table updates in real time.
