HTML to MATLAB Converter

About HTML to MATLAB Converter

Convert HTML tables and structured data to MATLAB code with support for matrices, cell arrays, and struct formats. Perfect for importing web data into MATLAB for analysis and visualization.

Key Features

• Multiple Output Formats: Matrix, cell array, or struct
• Table Extraction: Automatically extracts data from HTML tables
• Header Support: Preserves table headers in output
• Type Detection: Automatically detects numeric vs. text data
• List Support: Converts HTML lists to cell arrays
• Custom Variables: Specify variable names for output
• Comments: Optional descriptive comments in code

How to Use

1. Input HTML: Paste HTML with tables or data or upload a file
2. Choose Format: Select matrix, cell array, or struct output
3. Set Variable Name: Specify the MATLAB variable name
4. Review Output: The MATLAB code updates automatically
5. Copy or Download: Use the Copy or Download button to save your .m file

Output Formats

• Matrix: Numeric 2D array (converts non-numeric values to 0)
• Cell Array: Mixed data types with strings and numbers
• Struct: Structured data with named fields from headers

Example Conversions

Matrix Format (Numeric Data)

data = [
    0, 25.5, 101.3;
    1, 26.2, 101.5;
    2, 27.8, 102.1;
];

Cell Array Format (Mixed Data)

data = {
    'Time', 'Temperature', 'Status';
    0, 25.5, 'Normal';
    1, 26.2, 'Normal';
    2, 27.8, 'Warning';
};

Struct Format (Named Fields)

data = struct();
data.Time = [0; 1; 2];
data.Temperature = [25.5; 26.2; 27.8];
data.Status = {'Normal'; 'Normal'; 'Warning'};

Supported HTML Elements

• Tables: Extracts data from <table> elements with headers
• Lists: Converts <ul> and <ol> to cell arrays
• Paragraphs: Extracts text content as cell array
• Headings: Includes heading text in output

Common Use Cases

• Data Import: Import web data into MATLAB for analysis
• Scientific Data: Convert experimental data tables
• Web Scraping: Process scraped HTML data in MATLAB
• Report Generation: Import data for MATLAB reports
• Data Analysis: Prepare web data for statistical analysis
• Visualization: Import data for plotting and graphing

Tips for Best Results

• Use Tables: HTML tables convert most accurately
• Include Headers: Table headers become field names in structs
• Numeric Data: Use matrix format for purely numeric data
• Mixed Data: Use cell array for mixed text and numbers
• Structured Data: Use struct for named fields and columns
• Variable Names: Use valid MATLAB variable names (alphanumeric + underscore)

MATLAB Compatibility

Generated code is compatible with:

• MATLAB R2006a and later
• GNU Octave (open-source alternative)
• All MATLAB toolboxes

Privacy & Security
