Use Google Sheets to access protected Excel files

Aim: To access hidden sheets in Excel files with protected structures using Google Sheets.

In an earlier post, I described how to unhide Very Hidden Sheets in Excel. That method does not work if the workbook structure has been protected.

01 Protect Excel Structure

In this example, Sheet 2 has been hidden & attempting to unhide it using the “Visual Basic for Applications” Editor will result in an error.

02 Unhide Sheet Excel

One way of working around this is to upload the Excel file to Google Drive & open it with Google Sheets.

03 Open Protected GSheets

Click on the All Sheets menu at the bottom to show all sheets regardless of Excel’s visibility setting.

04 Unhide Sheets

Click on the greyed-out Hidden Sheet to open it. Allow the file to save, then return to the Google Drive folder.

05 Unhidden GSheets

Download the newly created Google Sheets version of the file.

06 Download GSheets

Open the downloaded file in Excel to see that the Hidden Sheet is now visible.

07 Open Protected Excel


Fortunately for security, Google Sheets cannot be used to open Excel files that have been encrypted.

11 Encrypt Workbook

When opening an encrypted workbook in Excel, you will be prompted to enter a password, without which the file will not open.

Uploading an encrypted file to Google Drive is supported.
