Link a range in one spreadsheet to a range in another and keep them identical from then on. Edit either side, the other updates — live, in both directions. No formulas or script required.
Edit either side of a link and the other updates automatically — no "source" and "copy," both stay current.
A single range can feed several targets at once — a hub setup where every link runs independently.
Real-time on every edit, on-demand with one click, or a fixed interval — your choice, per spreadsheet.
Blocks a new link if it would partially overlap another — stops two unrelated sheets from silently cross-propagating.
Auto-detected sheet names, Google's own file picker, and a simple dialog — set up in seconds, no IMPORTRANGE fragility.
