xlsx2html

What it is and what it does

xlsx2html is a lightweight Python converter that reads Excel workbooks and outputs them as HTML tables. It wraps openpyxl for reading .xlsx files and uses babel for locale-aware formatting of numbers and dates. The package is designed for straightforward export scenarios where you need to turn spreadsheet data into web-viewable HTML while maintaining basic cell formatting.

The library supports multiple input/output modes: reading from file paths, working with file-like objects in memory, or running as a command-line tool. It's in Alpha status and actively maintained, supporting Python 3.6 through 3.14 and PyPy. With no known vulnerabilities and permissive MIT licensing, it's a low-risk choice for simple xlsx-to-html pipelines.

Use it for:

• Export financial reports or data tables from Excel to embed in web dashboards or email templates.
• Batch convert spreadsheet archives to HTML for archival or documentation purposes.
• Generate HTML previews of uploaded Excel files in web applications without server-side rendering.
• Automate spreadsheet-to-web workflows where cell formatting (alignment, number display) matters.
• Convert locale-specific spreadsheets (e.g., European number formats) to correctly formatted HTML tables.

Quickstart

pip install xlsx2html

from xlsx2html import xlsx2html

# Convert to stream
out_stream = xlsx2html('path/to/example.xlsx')
out_stream.seek(0)
html_output = out_stream.read()

# Or write directly to file
xlsx2html('path/to/example.xlsx', 'path/to/output.html')

Verify before relying

• Whether cell formatting preservation includes colors, fonts, borders, or only basic alignment and number formats.
• Performance characteristics when processing large spreadsheets (row/column limits, memory usage).
• Support for merged cells, formulas, or other advanced Excel features.
• Locale parameter behavior and which locales are supported beyond 'en'.
