Advanced HTML Table to JSON Converter

HTML Table to JSON Converter - Smart Table Conversion

Our intelligent HTML Table to JSON Converter specializes in transforming HTML tables into clean, structured JSON arrays. Unlike generic converters, our tool automatically detects tables and converts them into arrays of objects - perfect for data extraction, API development, and data processing workflows.

Smart Table Detection & Conversion

• Table to JSON Array: Automatically converts HTML tables to arrays of objects
• Header Detection: Intelligently identifies table headers from <th> tags or first row
• Complex Table Support: Handles tables with thead, tbody, rowspan, and colspan
• Special Character Preservation: Correctly handles ©, ®, À, Á and other special characters
• Empty Cell Handling: Properly converts empty cells to null or empty strings

Example Conversion

Input HTML Table:

<table>
  <thead>
    <tr>
      <th>Character</th>
      <th>From Windows-1252</th>
      <th>From UTF-8</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>©</td>
      <td>%A9</td>
      <td>%C2%A9</td>
    </tr>
  </tbody>
</table>

Output JSON:

[
  {
    "Character": "©",
    "From Windows-1252": "%A9",
    "From UTF-8": "%C2%A9"
  }
]
