How to Fix Excel Opening Multiple Files and the .localized Error
Product
Microsoft Excel
Device & OS
macOS
Scenario
Launching Microsoft Excel after a system or software update.
Observed behavior
The application displays an access error for a hidden system file (.localized) and automatically opens approximately ten unexpected workbooks upon startup.
Before you start

Before modifying your Excel startup preferences, close all currently open workbooks and ensure your Office application is fully updated to the latest version.

Solution 1Recommended

Clear the Startup Folder Preferences

Removing the designated startup folder stops Excel from automatically attempting to load all files stored in that specific directory.

When Excel is configured to open all files in a broad directory like your Documents folder, it will try to open every supported file, as well as hidden system files like '.localized', causing access errors and a cluttered workspace.

1
Open Excel Preferences

Launch Microsoft Excel. Click on 'Excel' in the top Apple menu bar and select 'Preferences' from the dropdown menu.

2
Navigate to General Settings

In the Preferences window, locate and click on the 'General' icon.

3
Clear the File Path

Find the field labeled 'At startup, open all files in'. If there is a folder path listed here (such as your Documents folder), select the text and delete it, or click the 'Clear' button if available.

4
Restart Excel

Close the Preferences window and completely quit Microsoft Excel. Relaunch the application to verify that it opens normally with only a single blank workbook.

Clear the Startup Folder Preferences
Quick Fix: Clearing this startup field is the most common and effective solution for the .localized file error on Mac.

Frequently Asked Questions

Why does Excel show a .localized file error on my Mac?

The .localized file is a hidden macOS system file used to translate folder names. If Excel is accidentally configured to open all files in a specific folder (like your Documents folder) at startup, it will attempt to open this hidden system file alongside your spreadsheets, resulting in an access error because it is not a valid workbook format.

How do I stop Excel from opening old files at startup?

You need to clear the startup folder preference. Go to Excel > Preferences > General, find the 'At startup, open all files in' text box, and delete any file path listed there. This prevents Excel from batch-loading files from that directory.

Will reinstalling Microsoft Office fix the multiple files opening issue?

Not necessarily. Preference files are often retained on your computer even during a standard uninstall. Clearing the startup preferences directly in the settings or resetting the Excel preferences file (.plist on Mac) is usually a faster and much more effective solution.
