What this version does
Compares shared columns, lists added and removed products and columns, and flags configurable price swings, currency changes, zero or unreadable prices, and changed availability or GTIN values.
What needs a separate check
Live store data, inventory accuracy, feed policies, images, and revenue impact. This tool does not publish, monitor, approve, or alter a catalog. TSV and CSV only; export XML or Excel to UTF-8 first.
