About this comparison
Values from the selected XLSX sheets or CSV/TSV records are shown. Excel references include original sheets, rows, and cells. Numbers are shown without formatting; simple zero-padding is preserved and dates use ISO format. Formulas require a values-only copy. Formatting and embedded objects are not compared. Items are matched by identifier. Record numbers refer to the source files, with the header as record 1. Only selected fields are highlighted. Units and currencies are not converted.
