The HTML table is parsed and converted to JSON format. Table headers become object keys, and table cells become values.
An HTML Table to JSON Converter is a powerful online tool that transforms HTML table markup into structured JSON (JavaScript Object Notation) data format. This conversion is essential for web developers, data analysts, and programmers who need to extract tabular data from HTML documents and use it in applications, APIs, or databases. JSON is a lightweight, language-independent data interchange format that's widely supported across programming languages and platforms.

HTML tables and JSON represent data in fundamentally different ways. HTML tables use a markup structure with tags like <table>, <tr>, <th>, and <td> to display tabular data in web browsers. JSON, on the other hand, represents data as key-value pairs and arrays, making it ideal for data exchange between systems.
The conversion process involves parsing the HTML table structure and mapping it to JSON format through several key steps:
| Step | Process | Description |
|---|---|---|
| 1. Parsing | HTML Analysis | The HTML table structure is analyzed to identify rows, headers, and cells |
| 2. Header Extraction | Key Identification | Table headers (<th>) are extracted to become JSON object keys |
| 3. Data Mapping | Value Assignment | Table data cells (<td>) are mapped to corresponding keys |
| 4. Structure Creation | JSON Formation | Data is organized into the selected JSON format (array of objects or object with arrays) |

Different JSON formats serve different purposes in data processing and application development:
| Format | Structure | Use Cases |
|---|---|---|
| Array of Objects | [{key: value}, {key: value}] |
Database records, API responses, data processing |
| Object with Arrays | {key: [values], key: [values]} |
Column-based data, charting, statistical analysis |
| Nested Objects | {parent: {child: value}} |
Hierarchical data, complex relationships |
Converting HTML tables to JSON with our online tool is simple and efficient:
Paste your HTML table code into the input area or upload an HTML file containing the table.
Choose between "Array of Objects" or "Object with Arrays" JSON format based on your needs.
Click the "Convert to JSON" button to transform your HTML table into structured JSON data.
Examine the generated JSON in the output area and preview the original table structure.
Copy the JSON to your clipboard or download it as a file for use in your applications.
Beyond basic conversion, advanced techniques can enhance your data processing workflow:
Automatically detect and convert data types (numbers, booleans, dates) during the conversion process.
Process complex tables with nested structures, merged cells, and hierarchical data.
Map table headers to custom JSON keys for better data organization and API compatibility.
This HTML Table to JSON Converter tool is built using modern web technologies to provide accurate and reliable conversions:
Convert scraped HTML tables from websites into structured JSON data for analysis and integration.
Transform static HTML table data into JSON format for REST API endpoints and microservices.
Convert legacy HTML table data into JSON format for importing into modern database systems.
Prepare tabular data for charting libraries and data visualization tools that consume JSON.
Our converter supports standard HTML tables with <table>, <tr>, <th>, and <td> elements. It handles tables with headers, multiple rows, and various content types. Complex tables with merged cells (rowspan/colspan) are processed with best-effort mapping.
The converter properly escapes special characters in JSON output according to JSON standards. HTML entities are decoded to their Unicode equivalents, and quotes, backslashes, and control characters are properly escaped to ensure valid JSON output.
Currently, the converter processes the first table found in the HTML input. For multiple tables, you can process them separately or modify the HTML to isolate each table before conversion.
The converter focuses on data content rather than visual formatting. CSS styles, colors, and visual attributes are not preserved in the JSON output. Only the structural data (headers and cell values) is converted.
Follow these guidelines when creating HTML tables for optimal conversion results:
