Upload two files to compare
File 1 is your source of truth. File 2 is the target (e.g. migrated data). The tool checks both directions — what's missing in F2 and what's extra in F2.

Map comparison columns
Select which columns to compare. Each row maps one column from File 1 to one column from File 2. Add multiple rows for a combined key — all mapped columns must match for a record to be considered identical.
Column Mapping
File 1 Column
File 2 Column
⚠ All mapping rows must have both columns selected, with no duplicates within each file.
Comparison Results
Both directions checked. Missing = in File 1 but not in File 2 (didn't migrate). Extra = in File 2 but not in File 1 (shouldn't be there).
