What this tool does

This tool turns a spreadsheet range into clean HTML table markup. Paste a copied range straight from Excel or Google Sheets, or upload a .xlsx, .xls, or .csv file (with a sheet picker for multi-sheet workbooks), and get a live preview alongside ready-to-use HTML, with options for headers, pretty-printed or minified output, optional ready-made styling, and automatic right-alignment of numeric columns.

How It Works

Pasted data is split on tabs (the format your clipboard holds after copying cells from a spreadsheet) into rows and columns. An uploaded file is parsed by a JavaScript spreadsheet library running entirely in your browser, which reads the workbook's sheets into the same row-and-column shape. From there, the first row becomes a <thead> with <th> cells if you've kept "first row is a header" checked, the rest become <tbody> rows of <td> cells, and every value is HTML-escaped so special characters like & and < render correctly instead of breaking the markup.

Problems it solves

Turning a spreadsheet range into HTML for a website, email, CMS, or documentation page without hand-writing table markup.
Converting a .csv export into a properly structured, styled HTML table.
Picking the right sheet out of a multi-tab workbook without opening it in a separate spreadsheet app first.
Getting numbers visually right-aligned like they are in a real spreadsheet, instead of left-aligned like plain text.

Frequently asked questions

›Does my file get uploaded to a server?

No. Both the paste and the file-upload path are parsed entirely in your browser using a JavaScript spreadsheet library, nothing about your data or file ever leaves your device.

›Why does pasting work better than typing the data in?

When you copy a range of cells in Excel or Google Sheets, the clipboard holds a tab-separated version of that range. Pasting it straight into the text box lets this tool rebuild the exact rows and columns automatically, no manual formatting needed.

›What happens with a workbook that has multiple sheets?

A sheet picker appears after you upload it, defaulting to the first sheet, so you can convert whichever sheet you actually need without opening the file in Excel first.

›What does "right-align number columns" actually detect?

It checks whether every value in a column (excluding the header) parses as a number, and if so, right-aligns that column, both in the preview and in the generated HTML, the way spreadsheets themselves display numeric data.

›Can I get just the bare table markup, with my own CSS?

Yes, uncheck "Include ready-made styling" and the tool outputs a plain, semantic <table> with no class names or inline styles, ready for your own stylesheet.
