Problem

Operations teams need to see what changed between two versions of a bill of materials or Excel table, which is error-prone to check by hand.

Context

tables_compare_app is a public portfolio project with a deployed demo. It demonstrates the comparison and change-tracking pattern acty.dev builds as an internal tool.

Inputs

Two Excel or BOM files to compare

Technical approach

The app loads two spreadsheets, aligns their rows, and reports added, removed, and changed entries through a comparison and merge UI, so a reviewer can see exactly what moved between versions.
