About Smart Merge
Combine multiple CSV files into one master dataset intelligently.
Stop copy-pasting manually. Smart Merge lets you upload 10, 50, or 100 CSV files and combines them into one.
It handles column mismatches (e.g., if File A has "Email" and File B has "E-mail") and harmonizes headers automatically.
Perfect for monthly sales reports, log consolidation, or combining split datasets.
