Replace Fragile IMPORTRANGE Chains With Fast, Editable Cross-Sheet Sync

Synchronizes and consolidates rows across multiple Google Sheets tabs and separate workbooks by writing clean, static values via Append, Primary-Key Upsert, or Full Mirror modes.

Chaining IMPORTRANGE across department sheets causes endless "Loading..." hangs, and typing in a single cell breaks the entire table with a #REF! error. SheetSync writes fast, static values directly inside your account with scheduled syncs and a one-time unlock.
