01Where it runs

Server-local Excel read and HTML generation

02File lifetime

A temporary per-request workspace is cleaned when processing ends.

03Known limits

Formulas may surface as values or text depending on the workbook, and advanced styling, charts, or macros are not converted into a full web application. Review the HTML before publishing.

04Verify after download

Open the result in a browser and check headers, empty cells, numbers, and dates. Add appropriate CSS before publishing it publicly.

Workspace

Upload your file to start

Ready

Sample files contain demonstration content only. They are included so you can test the workflow before using your own data.

INFINITY INTELLIGENCE

A copilot that understands this tool.

Ask what a setting means, whether this is the right tool, how to recover from an error, or what to do with the result next. Infinity receives safe context from this page — not the file contents automatically.

PRACTICAL CONTEXT

What this tool is good at — and where to be careful.

BEST FOR

When this tool makes sense

Turning spreadsheet data into HTML tables that can be previewed or used as a starting point for a web page.

HOW IT WORKS

What the engine actually does

The XLSX is opened with openpyxl, cell values are read, and HTML is generated to represent the tabular content. The goal is data transfer rather than reproducing every Excel style or macro.

LIMITS

What it does not promise

Formulas may surface as values or text depending on the workbook, and advanced styling, charts, or macros are not converted into a full web application. Review the HTML before publishing.

CHECK

A 20-second quality check

Open the result in a browser and check headers, empty cells, numbers, and dates. Add appropriate CSS before publishing it publicly.

Frequently asked questions

Does it preserve every Excel style?

No. The workflow focuses on tabular data structure rather than full visual emulation.

Does it run macros?

No. Workbook data is read without executing macros or embedded code.

Clear limits

Supported formats and limits are shown before you start.

No cloud file history

Public conversions are designed around temporary request workspaces, not permanent file storage.
