Measure twice, make once
Live row counter
Keep one confirmed count synchronized wherever this counter link is open.
Start with the calculator. Formula, assumptions, and limits are available when you need them.
Before you use this tool
Decide whether the number means completed rows or the next row, and keep that convention. For completed rows, start at 0 and add 1 after finishing a row.
Reset starts a new count. Check connection status before trusting a shared count; everyone holding its link can change it.

The counter works locally and stores its value in this browser while offline. Anyone with the shared link can change the synced counter; do not use it for private or sensitive information.
