Question details

The user wants to know why Excel displays a smaller save dialog for XML files and a larger Save As window for XLSX files when closing documents exported from Microsoft Dynamics 365, and whether it can be forced to always use the smaller window.

Why Excel Shows Different Save As Windows for XML and XLSX Files
Product
Microsoft Excel
Device & OS
not provided
Scenario
Closing XML and XLSX spreadsheet files that were exported from Microsoft Dynamics 365.
Observed behavior
Excel displays two different save dialogs depending on the file type. XML files show a preferred smaller dialog, while XLSX files prompt a larger Save As window.
Before you start

Before adjusting your settings, note that Excel's save dialog behavior heavily depends on the file's original format, whether it was temporarily cached by your browser, and the source application (such as Microsoft Dynamics 365).

Solution 1Recommended

Configure 'Save to Computer by Default' Setting

While this will not completely eliminate the large Save As window for all file types, setting your default save location to your local computer can streamline the saving process.

Excel often defaults to cloud locations (like OneDrive or SharePoint), which triggers the larger backstage Save As window. Forcing local saves helps bypass this in some scenarios.

1
Open Excel Options

Launch Microsoft Excel, click on the 'File' tab in the top-left corner, and select 'Options' at the bottom of the menu.

2
Navigate to Save Settings

In the Excel Options window, click on the 'Save' tab in the left-hand navigation pane.

3
Enable Local Saving

Check the box that says 'Save to Computer by default'. Additionally, you can uncheck 'Show additional places for saving, even if sign-in may be required'.

4
Apply Changes

Click 'OK' to save your settings. Test closing a new file to see if the save prompt behavior has improved.

Configure 'Save to Computer by Default' Setting
Limitation: Excel does not provide a built-in feature to universally force the smaller save dialog. Files that have not been saved locally before (like fresh XLSX exports) will still trigger the larger window.

Frequently Asked Questions

Can I force Excel to always use the small save dialog?

No. Excel does not currently offer a universal setting to force the smaller save dialog. The prompt style depends on the file format, origin, and whether it has an existing local save path.

Why does an exported XML file show a different save prompt than an XLSX file?

When you export an XML file from platforms like Dynamics 365, your web browser often caches it in a temporary local folder first. Because it has an existing local path, Excel shows a simple save prompt. Unsaved XLSX exports are often treated as completely new files, triggering the larger Save As window.

What does 'Save to Computer by default' actually do?

This setting forces Office applications to prioritize your local hard drive over cloud services like OneDrive when you open the Save As menu. However, it does not change the visual interface of the save prompt for files that require a new location.
