How do I convert an HTM file to CSV using LetsConvert?

Upload your HTM file by dragging it into the converter or clicking 'Choose File'. Select 'CSV' as the target format. Hit 'Convert'—the tool will automatically extract all table data from the HTML structure. Once the conversion finishes, download the .csv file to your device.

Why should I convert HTM to CSV instead of keeping it as HTML?

HTML is designed for web rendering, not data analysis. CSV is a plain-text tabular format that imports directly into Excel, Google Sheets, SQL databases, and Python/R analytics pipelines. Converting strips away markup and scripts, reducing file size and eliminating the need to parse HTML tags manually. This makes data aggregation, filtering, and sharing far more efficient.

How does the converter handle merged cells, HTML entities, and inline styles during HTM to CSV conversion?

Merged cells (rowspan/colspan) are expanded into empty placeholders so the CSV grid stays rectangular. HTML entities like & and < are decoded to & and <. Inline styles, JavaScript, and CSS classes are removed because CSV supports only columnar text data. Cell content that contains commas or newlines is wrapped in double quotes per RFC 4180 to preserve data fidelity.
