What happens to sheets with the same name?
They're never overwritten — a colliding sheet name is automatically renamed, e.g. "Sheet1" and "Sheet1 (2)", so every worksheet from every file ends up in the merged workbook.
Is formatting, like colors, fonts, and column widths, preserved?
Yes — Merge Excel works at the file-package level (not by reading and rewriting cell data), so each worksheet's fonts, fills, borders, number formats, merged cells, column widths, row heights and freeze panes carry over. A small number of advanced features (custom color themes after the first file, pivot tables, external workbook links) aren't guaranteed — the tool tells you exactly if any of these were found.
Is my spreadsheet uploaded anywhere?
No. Every workbook is read and merged entirely in your browser.
