Combine multiple Excel or CSV files into one sheet. MergeSync lines up columns automatically — even when files name them differently ("E-mail" vs "Email Address", "Zip" vs "Postal Code") — and lets you adjust the mapping before merging.
1

Drag & drop two or more spreadsheets

Each row becomes one column in the merged file. Columns were matched automatically — change any dropdown to fix a match, rename the merged column, or remove it.
