How to Convert HTML Tables to JSON
- 1
Paste Your HTML Table
Copy the HTML table code from your source, whether from a webpage using browser developer tools, a saved HTML file, or your own code. Paste it into the input area on the left. - 2
Choose Your Output Format
Select either Array of Objects for key-value pair output using column headers as keys, or Array of Arrays for a simple two-dimensional array structure without named keys. - 3
Configure Header Settings
Toggle the first row as headers option. When enabled, the first row values become JSON object keys. When disabled, automatic column names like column1 and column2 are generated. - 4
Convert and Copy the Result
Click Convert to JSON to generate the output. Review the formatted JSON in the output panel, then copy it to your clipboard for use in your application, API, or data pipeline.
Common Use Cases
Web Scraping and Data Extraction
API Development and Testing

Why Convert HTML Tables to JSON?
The HTML Table to JSON Converter transforms HTML table markup into clean, structured JSON data instantly in your browser. Whether you are extracting data from a website, migrating content between systems, or building an API, this tool eliminates the tedious process of manually parsing table rows and cells. Paste any valid HTML table and get well-formatted JSON output in seconds, with no server uploads and no signup required.
This tool supports two output formats: Array of Objects, where each table row becomes a JSON object with column headers as keys, and Array of Arrays, which produces a simple two-dimensional array. Both formats are widely used in JavaScript applications, REST APIs, and data processing pipelines. For further data transformation, pair this tool with the JSON Formatter to validate and beautify your output, or use the JSON to CSV Converter to export the data into spreadsheet-compatible format.
Developers frequently use this converter as part of web scraping workflows. After retrieving HTML content from a page, extract the table markup and convert it here to get structured data ready for storage or analysis. For the reverse operation, converting structured data back into HTML tables, check out the JSON to Markdown Table generator or the Markdown Table Generator. If you are working with other data formats, the CSV to JSON Converter handles delimited text files with the same ease.
How It Compares
Unlike many online HTML-to-JSON converters that require account creation or impose daily conversion limits, the FindUtils HTML Table to JSON Converter is completely free with unlimited usage. All processing happens client-side in your browser, so your data never leaves your device. This makes it a safer choice for converting tables that contain sensitive information such as financial reports, customer data, or internal metrics.
Compared to writing custom parsing scripts with libraries like Cheerio, BeautifulSoup, or browser-based DOMParser code, this tool gives you instant results without any setup. It handles common edge cases like missing headers, empty cells, and mixed content automatically. For developers who need programmatic access, the JSON output can be copied directly into your codebase or piped into tools like the jq Playground for further transformation and filtering.
