Calrows
Calrows is a Google Sheets add-on. Keep your schedule, shifts, bookings or deadlines in a sheet, click once, and they appear on your calendar. Edit either side and sync again. No account to create, no surprise paywall, and every run is logged.
Install from the Google Workspace Marketplace See pricing
Map your columns once. Title, start, end, all-day, description, location, guests, colour. Re-run any time: rows already synced are updated, never duplicated.
Moved an event in Calendar? One click writes the new time back into the row.
Pick a calendar and a date range, get a clean sheet of events. Never "all fifteen years" unless you ask for it.
Turn a month of calendar events into hours, rates and amounts, with totals per client.
Pro: runs every 15 minutes to once a day in the background, even with the sheet closed.
A Sync Log tab records every event created, updated, removed or failed, with the row number and the reason.
The Marketplace has calendar add-ons with millions of installs and ratings under two stars. The reviews say the same things: "free" apps that charge after one use, syncs that die with "exceeded maximum execution time", imports with no date range, and support that never answers. Calrows was built against that list.
