How to Use This HTML Table to CSV Converter
Converting HTML tables to CSV format is straightforward with this tool. Simply paste your HTML table markup into the input area, configure your CSV formatting preferences, and export the structured data.
- Paste HTML Table Code: Copy the complete HTML table markup from your source, including opening and closing <table> tags. The tool accepts tables with headers (<th> elements) and standard data cells (<td> elements).
- Configure Export Options: Choose whether to include table headers as the first CSV row, select your preferred delimiter (comma, semicolon, tab, or pipe), and decide whether to quote all fields or only those containing special characters.
- Generate CSV: Click the convert button to process the HTML table and generate properly formatted CSV output that follows standard conventions for maximum compatibility.
- Download or Copy: Save the converted data as a CSV file for use in spreadsheet applications, databases, or data analysis tools. The output maintains the table structure while ensuring proper escaping of special characters.
The tool handles various HTML table structures and automatically cleans up formatting issues, making it ideal for extracting tabular data from web pages, emails, and applications for further processing.
How It Works
The HTML Table to CSV Converter processes HTML markup through several steps to ensure clean, properly formatted output:
- HTML Parsing: The tool creates a DOM representation of your HTML table markup, identifying table structure including headers, rows, and cells while handling nested elements and extracting text content.
- Data Extraction: Each table row is processed to extract cell values, with HTML tags stripped and entities decoded. The converter handles both <th> and <td> elements, organizing data into a structured grid format.
- CSV Formatting: Cell values are formatted according to CSV standards, with special characters properly escaped and fields quoted as needed. The selected delimiter is applied consistently throughout the output.
- Output Generation: The final CSV data is assembled with proper line endings and encoding, ready for download or copying to other applications. Headers are included or omitted based on your settings.
All processing happens locally in your browser, ensuring your data remains private while providing instant conversion results for tables of any reasonable size.

Frequently Asked Questions
What HTML table elements are supported for conversion?
The converter supports standard HTML table elements including <table>, <thead>, <tbody>, <tr>, <th>, and <td> tags. It handles nested tables by processing only the outermost table structure. Complex styling, merged cells (colspan/rowspan), and embedded HTML elements within cells are simplified during conversion to ensure clean CSV output.
How does the tool handle special characters and formatting in table cells?
The converter automatically escapes special characters like commas, quotes, and line breaks according to CSV standards. HTML entities are decoded to their proper characters, and any HTML tags within cells are stripped to leave only text content. You can choose to quote all fields or only those containing special characters for maximum compatibility with spreadsheet applications.
Can I convert tables with merged cells or complex layouts?
While the tool can process tables with colspan and rowspan attributes, merged cells are flattened into individual CSV cells. For complex table layouts, the converter extracts visible text content and organizes it into a regular grid structure. Tables with irregular layouts may require manual cleanup after conversion for optimal results.
What delimiter options are available for the CSV output?
The tool supports common CSV delimiters including comma (,), semicolon (;), tab, and pipe (|). Comma is the standard delimiter for most applications, while semicolon is commonly used in European locales. Tab-delimited format works well for importing into databases, and pipe delimiters are useful when data contains commas and semicolons.
How large can the HTML table be for successful conversion?
The converter can handle tables with thousands of rows and hundreds of columns, limited primarily by your browser's memory capacity. For very large tables (over 10MB of HTML), processing may take several seconds. The tool works entirely in your browser, so no data size limits are imposed by server restrictions, but extremely large files may cause performance issues on older devices.
