Excel to HTML
Open an Excel or CSV file and convert a sheet to an HTML table. The file is read locally and never uploaded.
Choose a file to preview its contents here.
How to use
Choose an .xlsx, .xls or .csv file and it is parsed in your browser and shown as a table. Workbooks with several sheets get a sheet selector. Copy HTML puts the same content on your clipboard as a plain HTML table (table, tr and td only). The preview — and the copied HTML — are capped at the first 500 rows.
Notes
The file is read only in your browser and is never uploaded. Cell contents are escaped before display, so text inside cells is never interpreted as HTML. Cell formatting (colors, fonts, borders) is not reproduced, formulas are shown as their computed values, and merged cells are treated as regular cells.
FAQ
What happens with more than 500 rows?
The total row count is shown and only the first 500 rows are previewed and copied, with an explicit note that the rest was truncated.
How are date cells shown?
As the string representation returned by the spreadsheet library, which may differ from the formatted display in Excel.
