Question details

The user wants to securely restrict access to specific sheets within a single Google Sheets workbook so that each office only sees its own data, while the head office retains access to a master sheet with all records.

Product: Google Sheets
Device & OS: not provided
Scenario: Sharing spreadsheet data securely among different branch offices and a head office.
Observed behavior: Google Sheets does not provide secure, reliable sheet-level or row-level privacy within a single shared workbook, allowing users to see data they shouldn't.

Before you start

Before reconfiguring your sharing settings or splitting your files, back up your original master workbook to ensure no data is accidentally lost or overwritten during the separation process.

Solution 1Recommended

Separate Data into Individually Shared Workbooks

Since Google Sheets does not support strict sheet-level privacy within a single file, separating the data into distinct files is the most secure method to maintain row-level and sheet-level privacy.

Google Sheets sharing and protected ranges are designed to restrict editing, not viewing. If multiple users have access to the same workbook, they can typically see all the data inside it, even if a sheet is protected or hidden.

To achieve true data isolation between different branch offices, you must break the single workbook into multiple files and use a master file strictly for head office operations.

Create Individual Office Workbooks

Create a new Google Sheets file for each branch office. Copy only the data relevant to that specific office into their respective new workbook.

Share with Specific Users

Click the 'Share' button in the top right corner of each new individual workbook. Add only the email addresses of the staff members who belong to that specific office, ensuring others cannot access it.

Isolate the Master Workbook

Keep your master workbook restricted. Remove all branch office staff from the sharing permissions of the master file, leaving only head office administrators.

Use IMPORTRANGE for Master Consolidation

In the master workbook, use the =IMPORTRANGE() function to securely pull data from the individual office workbooks. This allows the head office to view everything centrally without giving branch offices access to the master file.

Data Privacy Limitation: Using 'Protected Sheets and Ranges' in a single workbook only prevents unauthorized editing; it does not hide the data from users who have view access to the file.

Frequently Asked Questions

Can I hide a specific sheet from certain users in Google Sheets?

No, Google Sheets does not support user-specific sheet hiding within a single workbook. If a user has permission to open the file, they can view all unhidden sheets and can easily unhide any hidden sheets.

Does protecting a sheet keep it secure from being viewed?

Protecting a sheet or range only restricts who can edit that specific area. It does not prevent other users who have access to the workbook from viewing the data.

How can I link separate Google Sheets together?

You can use the IMPORTRANGE function to pull data from one Google Sheets file into another. This allows you to maintain separate, secure files for different users while automatically consolidating all their data into a private master sheet.

Can I use password protection on individual sheets in Google Sheets?

Google Sheets does not offer a built-in feature to password-protect individual sheets. Data privacy is strictly managed at the file level via sharing permissions.
