Yes. Excel Sheet Merger is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.

Does Excel Sheet Merger upload your file to a server?

No. Excel Sheet Merger processes your file inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
