Usage Guide
Excel is the team spreadsheet workhorse, but web pages and emails cannot embed .xlsx directly — conversion to HTML tables is necessary. This tool turns Excel content into clean, semantic HTML table code preserving merged cells and basic styling, with local file processing.
1. How to use
- Drag a .xlsx or .csv file into the tool (or paste tabular data from clipboard).
- The tool auto-detects header rows and data area, generating semantic <table> HTML.
- Toggle border, background color and alignment styling options, then copy the HTML output.
2. When to use this conversion
- Pasting data tables into email: paste the HTML table directly into Outlook or Gmail for native rendering.
- Embedding data into static pages: insert converted tables into Next.js or Hugo without extra CSS frameworks.
- CMS content: WordPress, Notion and other rich-text editors accept direct HTML table paste.
- Pre-clean your Excel first — too many merged cells will break the HTML layout; flatten into regular rows and columns.
3. Semantic HTML tables matter
The output should contain <thead>/<tbody>/<th> semantic tags rather than <div>-based table simulation — this affects accessibility (screen readers rely on semantics) and SEO (search engines recognize table structure). If headers are in the first row, <th> is generated automatically; if headers span multiple rows or are irregular, verify the <thead> content after conversion.
