Is my spreadsheet uploaded anywhere?

No. The conversion runs 100% in your browser using SheetJS and an in-browser PDF writer — no spreadsheet bytes are sent to a server. You can confirm it in your browser's network tab.

Does it keep my numbers, dates and currency formatting?

Yes. AttachKit reads each cell's displayed (formatted) value — so dates, currency and percentages appear exactly as they do in Excel, not as raw numbers.

What isn't carried over?

Charts, cell background colors, conditional formatting and embedded images aren't reproduced — the converter renders a clean text-and-grid table. For pixel-perfect layout you'd need a server-side rendering engine, which would mean uploading your file.

Is there a size limit?

Because everything runs on your device, very large workbooks are capped (the first several thousand rows and columns per sheet) so the browser tab stays responsive; you'll see a note if a sheet was clamped.

Yes — unlimited Excel-to-PDF conversions, no account and no watermark.

Nothing is uploaded

The whole thing runs in your browser — open your network tab and watch: your file never leaves your device. Most online tools round-trip your document through their servers.

A faithful, paginated grid

Every sheet is drawn as a real bordered table with a styled header row and your cells' formatted values (dates, currency, percentages). Wide sheets switch to landscape and paginate across pages automatically.
