HTML to JSON converter for nested HTML element data
The HTML to JSON converter walks the document body and turns its structure into a nested JSON object. Each HTML element is represented with its tag, attributes in an attrs field, and child content in a children field; text is included in the serialized tree. Paste HTML, review the available options, and copy the JSON output for use in another tool or in code.
The HTML to JSON converter walks the document body and serializes its structure as a nested JSON object. Each element becomes an object with a tag, attrs, and children, so the output gives developers a structured view of the HTML rather than a block of markup. Use it to convert HTML to JSON online and copy the result for another tool or for your code.
The conversion represents element names as tags, element attributes in an attrs field, and nested content through children. Text is included in the serialized tree. You can adjust the available options before conversion, then review the generated JSON to make sure its structure suits your task. The tool’s workflow is to paste HTML, configure any options, generate the result, and copy it.
HTML describes document content using markup, while JSON represents data using objects, arrays, and values. Converting HTML to JSON can help when a system accepts JSON rather than markup, or when you want to inspect HTML structure in a data-oriented format. The result makes tags, attributes, and child relationships visible in a nested representation.
The conversion runs entirely in your browser: the input is processed on your device and is not uploaded, stored, or sent to a server. The tool also works offline once the page has loaded, so a connection is not needed for the conversion itself. This browser-based workflow is useful for developers and DevOps engineers who need to prepare or inspect HTML data without sending it elsewhere.
Step 1: Paste your HTML input
Step 2: Adjust any options
Step 3: Copy the JSON result
Use case: Move HTML data into a system that only accepts JSON.
Use case: Check that a JSON value you were handed really matches the HTML original.
Use case: Prepare HTML snippets for documentation, a ticket, or a commit message.
Use case: Sanity-check a conversion before pasting the result into code.
