Migrate from Microsoft 365 to Google Workspace without breaking your existing workflows. A practical guide.

If you look at the IT roadmap of most mid-to-large enterprises, the goal is usually standardization: migrate from Microsoft 365 to Google Workspace.

This isn’t because the migration strategy failed; it’s because the tools are technically distinct, and forcing an immediate full switch often creates more problems than it solves.

• Finance and Data Science teams stick to Microsoft Excel because of its superior calculation engine. It handles local processing of heavy datasets (500k+ rows) and legacy VBA macros better than browser-based alternatives.
• Marketing, Product, and Ops teams gravitate toward Google Sheets for its concurrency. They need the QUERY function, true real-time collaboration without locking the file, and native integrations with tools like BigQuery or Google Analytics.

In most Microsoft-to-Google Workspace migrations, full cutover almost never happens overnight. Finance usually keeps critical models in Excel files stored in OneDrive or SharePoint, while operations, leadership, and reporting teams start shifting to Google Sheets and Docs. The result is a hybrid phase that looks manageable on paper but creates daily headaches until data flows smoothly between the two.

Why Does the Full Cutover to Google Workspace Often Fail?

The failure isn’t in the strategy; it’s in the data structure. When you split your organization between Microsoft (legacy data) and Google (operational data), you create a Data Gap.

Consider a standard Month-End Close scenario during a migration:

1. Finance finalizes the OPEX report in a complex Excel model hosted on SharePoint.
2. Department Heads (now on Google Workspace) need those numbers in a Google Sheet to track against their live budgets.

Because these two systems don’t communicate, the migration effectively breaks the workflow. Finance has to manually export PDFs or CSVs and email them to the Google users. This introduces latency (data is always stale) and integrity risk (human error during copy-pasting). To save the migration, we don’t need to force Finance into Google Sheets immediately. We need to build an automated bridge that lets them keep Excel while feeding live data to the rest of the company in Google Workspace.

What is the Solution to this Problem?

This is where Sheetgo enters the migration architecture. Sheetgo is the interoperability layer that keeps data flowing during and after your move to Google. It functions as middleware that establishes a secure, authenticated pipeline between Microsoft 365 (OneDrive/SharePoint) and Google Workspace (Drive).

Unlike scripts (such as Google Apps Script) that break when APIs change, Sheetgo manages the connection lifecycle. It allows you to treat a SharePoint Excel file as a direct database source for a Google Sheet.

The result: The Finance team keeps their Excel models, but the data inside them becomes instantly available to the Google Workspace teams.

Practical Implementation: Building the Pipeline

The Scenario 

We will automate a Sales Commission Calculation workflow.

• Source: A master Closed Deals ledger kept in Excel (OneDrive/SharePoint) by the Finance team. They refuse to migrate this because it links to other Excel-based accounting ledgers. 
• Destination: A Google Sheet dashboard used by Sales Directors to view real-time commission payouts.

Step 1: Create Workflow and Select File Type

In your Sheetgo home page, click on +New and click on Create a Workflow.

Next, click Add to Workflow, and then select Automation.

You will immediately see the available interoperability options. Unlike standard importers, Sheetgo treats cloud storage (SharePoint, OneDrive, Drive) as database sources. Go ahead and click on Excel.

Step 2: Connect to OneDrive

Once the file type (Excel) is selected, Sheetgo will prompt you to enter the file location. This is the point at which the hybrid capability is utilized. Click on Select File.

Select SharePoint or OneDrive for Business. If this is your first time, you will do a one-time OAuth authentication. You do not need IT to generate API keys; simply log in with your Microsoft 365 credentials.

Step 3: Select the File (Workbook) and Tab (Worksheet)

Navigate your folders in the Sheetgo interface and select the desired Excel file as your data source. You select the specific Tab (Worksheet) you want to pull data from. Select the exact file and tab you need to extract data from.

Step 4: Data Processing (Optional)

After selecting your data, you will see the Select a data processor screen. This is Sheetgo’s transformation engine. In advanced workflows, you would use this screen to:

• Filter rows: (e.g., Only pull rows where Region = “NA”).
• Remove duplicates: Clean up messy data before it hits the destination.
• Process with AI: Use LLMs to categorize or tag data automatically.

Action: Since we want to establish a direct feed of raw data to our dashboard, we don’t need to filter anything yet. Click the Skip data processor button at the bottom right to proceed.

Step 5: Transfer to Google Sheets (The Destination)

Now that Sheetgo is holding the Excel data, we tell it where to send it.

1. Click Next to choose your destination.
2. Select Google Sheets as the file type.
3. Choose Google Drive as the location.
4. Select Create new spreadsheet and name it Sales_Commissions_Live.
5. Once done, click on Review Automation.

Review Automation

You will see a summary of your connection (Source: Excel, Destination: Google Sheets). Click Finish and run to execute the transfer immediately.

Workflow trigger settings

The Air Gap is only closed if the data flows without human intervention. Toggle the Enable automatic updates switch. For a commission report, setting this to run on an Hourly Basis is usually sufficient. Sheetgo will now check the OneDrive file for changes on that schedule and automatically update the Google Sheet.

In just a few moments, your live Excel data is ready for analysis. To view your results, you have two easy options:

• From the Sheetgo: Your destination file in the workflow view is now a clickable link. Simply click on the file icon to open your new Sales_Commissions_Live spreadsheet directly.
• In your Google Drive: Locate the Sales_Commissions_Live spreadsheet in your Google Drive. This spreadsheet now contains a tab populated with your fresh Excel records, ready for you to build pivot tables, generate charts, or share with your team immediately.

Workflow Variation 2: Filtered Regional At-Risk View

In the example above, we mirrored the full data. But what if you only need specific rows? 

Finance maintains the full master ledger in Excel on SharePoint, containing all 20 global deals. However, Regional VPs often only care about their specific area—e.g., pending North America deals—to spot audit flags without wading through EMEA/APAC noise.

This variation shows how to pull the same source but apply filters so the destination Google Sheet gets a clean, summarized view automatically.

• Source: Same as before (Master_Ledger.xlsx in OneDrive).
• Step 4 (Data Processing): Instead of skipping, select Filter Rows.
• Add Logic:
• Condition 1: Column Region is exactly NA
• Condition 2 (AND): Column Status does not contain Paid

This combination keeps only NA deals that are still in flux (e.g., Pending, Audit, Held), reducing the output from 20 rows to ~4–5 high-attention records. 

Destination: Push to a new or existing Google Sheet, e.g., “NA_At_Risk_Summary_Live”, tab “Exec Overview”. Use Replace mode for clean refreshes.

Review Automation & Run (same as above): Review the summary, click Finish, and Run. The filtered data lands in your Google Sheet or can be fetched automatically on schedule.

After a successful run, your destination Google Sheet tab will show only the filtered rows that match both conditions. Here’s what the output looks like based on the sample ledger data (filtered to Region = NA and Status does not contain “Paid”):

This slimmed-down table (just 2 rows in the sample) gives executives an instant view of high-attention NA commissions that are still pending or under audit—fresh every hour, with no manual filtering required. Finance continues editing the master Excel file; any new matching deals will appear automatically in the next update.

How Does This Approach Accelerate Your Migration to Google Workspace?

The commission workflows above are just one pattern. Sheetgo creates a governed, automated interoperability layer that supports phased migration: Finance keeps Excel during transition, while teams in Google Workspace get live data without silos or handoffs.

By placing Sheetgo at the center, you transform fragmented coexistence into a unified flow—Excel power for finance, Sheets collaboration for ops/sales/leadership. Data moves reliably, trust builds, manual errors vanish, and migration risk drops. Hybrid becomes the safe bridge to full Google Workspace adoption, not a permanent state.
