SheetBridge - Two-Way Notion to Google Sheets Sync

Notion and Sheets, always in sync

For
Data analysts and small analytics teams who keep data in both Notion databases and Google Sheets
Who are
Frustrated by manual copy-paste and CSV round-trips, automations that fail or take hours to debug, and task-based pricing that runs out within days
We build
A Google Workspace Add-On that keeps Notion databases and Google Sheets in real-time two-way sync, with per-field controls, a plain-language sync log and flat, predictable pricing
Unlike
Zapier, which is task-based, burns through usage limits in days, and is hard to debug and to cancel
Whalesync, which has pricing that does not fit every use case, cryptic API errors and coarse sync toggling
Unito, which focuses on project-management items, drops some fields and lacks cross-flow sync history
We deliver
Two-way Notion-Sheets sync set up in minutes without code, directly inside Google Sheets
A per-record sync log and field-support warnings so errors can be traced quickly
Flat, predictable pricing with usage alerts before limits are hit
So that
Data analysts can stop manually updating data, trust that both tools show the same numbers, and spend their time on analysis
Revenue potential
$30K MRR
Build time
8-12 weeks
Target market
Global data analysts and small analytics/ops teams in SMBs and agencies who use Notion databases alongside Google Sheets (Google Workspace users)

The Problem

Data analysts keep the same data in Notion and spreadsheets and update it by hand, which is time-consuming and error-prone: "It saves us a bunch of time that we used to spend copying and pasting." General automation tools are the workaround, but they "would often fail or I'd spent time trying to track down errors" and burn through task limits within days.

“Previously, publishing or making changes to our website content was a time-consuming and error-prone process.”

Connor M.

“We are using Unito to solve the problem of having items worked in different tools by different teams mirrored to each other to prevent manual duplication and out-of-sync statuses.”

“We found out after the fact that images and code snippets in the Description did not sync, and were omitted.”

G2 Review โ†—
Lucia L.

“You are not able to see history of all syncing, so if you have for example 2 Trello boards connected to 1 board, and in that one board is something synced wrong, you cannot find in which flow is the mistake and you need to check all of them.”

“I spent four hours debugging a broken Zap when I should have been on the gym floor fixing equipment, honestly.”

“It is extremely overpriced and you will go through your zap limit in days if you're using it fully.”

“You get 750 tasks which get used up in 3 days with only two zaps (flows).”

“Whalesync lets us edit our CRM (Salesforce) from a new spreadsheet which makes it so that we can bulk edit our deals and most of the team does not need to login to Salesforce.”

Competitors

Direct Competitor Zapier Zapier

General-purpose, task-based workflow automation platform increasingly pitched as an AI automation platform (Copilot, Canvas, Agents). Reviewers use it to sync CRMs and spreadsheets, but it is not a purpose-built two-way sync tool.

Weaknesses
Task and usage limits are exhausted within days, even on simple multi-step flows, Automations fail or break in production, and debugging can take hours, Too complex for some non-technical users, who switched to IFTTT or direct API/AI-built code

It is extremely overpriced and you will go through your zap limit in days if you're using it fully.

Direct Competitor Whalesync Whalesync

No-code, two-way, real-time data sync between tools such as Airtable, Notion, Webflow, Salesforce and Google Sheets. Reviewers contrast it with Zapier as more reliable and easier for syncing.

Unito Unito

Weaknesses
Some fields are omitted in sync (images and code snippets in Jira descriptions), No history across all syncs makes it hard to trace where a mistake came from, Described as buggy by some reviewers
