How It Works
- 1
Paste JSON Array with Consistent Structure
Paste your JSON array where each object has the same keys. Works with API responses, database query results, or any tabular JSON data structure.
- 2
AI Generates Semantic Table HTML
The tool creates proper HTML table structure with thead for headers, tbody for rows, and appropriate CSS classes for styling with Bootstrap or Tailwind.
- 3
Copy HTML for Web Pages
Copy the generated table HTML and paste into your HTML, React JSX, or Vue template for instant data display with proper accessibility.
JSON vs HTML Table: Display Comparison
| Feature | JSON | HTML Table |
|---|---|---|
| Format | Data structure | Visual table |
| Display | Text/code | Grid layout |
| Sorting | Not visual | Add JS for sorting |
| Styling | N/A | CSS classes |
| Use Case | Data storage | Web page display |
| Accessibility | Screen readers struggle | Semantic HTML |
Code Examples
Example 1: Simple User List
[
{"Name": "Alice", "Age": 28, "Role": "Engineer"},
{"Name": "Bob", "Age": 34, "Role": "Designer"},
{"Name": "Carol", "Age": 25, "Role": "Manager"}
]<table class="table table-striped">
<thead>
<tr>
<th>Name</th>
<th>Age</th>
<th>Role</th>
</tr>
</thead>
<tbody>
<tr>
<td>Alice</td>
<td>28</td>
<td>Engineer</td>
</tr>
<tr>
<td>Bob</td>
<td>34</td>
<td>Designer</td>
</tr>
<tr>
<td>Carol</td>
<td>25</td>
<td>Manager</td>
</tr>
</tbody>
</table>Key Changes:
JSON object keys (Name, Age, Role) convert to table headers in <thead>. Each array element becomes a <tr> row with <td> cells for values. The converter adds Bootstrap classes like 'table table-striped' for styling. The semantic HTML structure is screen-reader accessible. This table can be enhanced with JavaScript libraries like DataTables for sorting, filtering, and pagination. Common use case: displaying user lists, product catalogs, or any API response data on web pages without manual HTML writing.
Example 2: Product Inventory with Links
[
{"ID": "P001", "Product": "Laptop", "Price": "$999", "Stock": 50, "Status": "Available"},
{"ID": "P002", "Product": "Mouse", "Price": "$29", "Stock": 200, "Status": "Available"},
{"ID": "P003", "Product": "Keyboard", "Price": "$79", "Stock": 0, "Status": "Out of Stock"}
]<div class="overflow-x-auto">
<table class="min-w-full divide-y divide-gray-200">
<thead class="bg-gray-50">
<tr>
<th class="px-6 py-3">ID</th>
<th class="px-6 py-3">Product</th>
<th class="px-6 py-3">Price</th>
<th class="px-6 py-3">Stock</th>
<th class="px-6 py-3">Status</th>
</tr>
</thead>
<tbody class="bg-white divide-y divide-gray-200">
<tr>
<td class="px-6 py-4">P001</td>
<td class="px-6 py-4">Laptop</td>
<td class="px-6 py-4">$999</td>
<td class="px-6 py-4">50</td>
<td class="px-6 py-4">Available</td>
</tr>
<!-- More rows -->
</tbody>
</table>
</div>Key Changes:
The converter generates Tailwind CSS classes for modern styling with proper spacing, borders, and responsive behavior. The outer div with overflow-x-auto enables horizontal scrolling on mobile devices. Header cells use px-6 py-3 padding for comfortable spacing. The divide-y utility adds subtle borders between rows. Stock values of 0 and Out of Stock status can be styled with conditional CSS classes for visual warnings. This HTML structure integrates seamlessly with React, Vue, or Next.js components. Add onClick handlers to rows for interactivity, or integrate with state management for real-time updates from WebSocket or API polling.
Frequently Asked Questions
JSON arrays convert to HTML <tr> rows where each object becomes a row. Object keys become <th> headers in <thead>. Values populate <td> cells in <tbody>. For example, [{"name": "John", "age": 30}] generates a 2-column table with name and age headers.
Yes. The converter generates HTML tables with optional Bootstrap or Tailwind CSS classes for responsive behavior. Tables adapt to mobile screens with horizontal scrolling or stacked layouts. You can customize CSS classes for your framework.
Nested objects convert to string representations in cells or can be expanded to separate columns. For deeply nested data, consider flattening JSON first. Arrays within objects display as comma-separated values. This works for most relational data display needs.
