I built this tool because I needed it myself — I was constantly merging 6-7 Excel sheets manually for work and every online tool I found either stripped the formatting, required uploads to some server, or wanted a subscription. So I made one that works right in the browser, keeps all formatting intact, and doesn't send a single byte anywhere. Hoping it saves you the same headache it saved me. If it helps even one person, it was worth building.
