Fix Excel VBA Error 'Value does not fall within the expected range' Connecting to Oracle
Question details
The user is experiencing a specific error when trying to connect to an Oracle database using Excel VBA.
- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Running an Excel VBA script to establish a connection with an Oracle database.
- Observed behavior
- An error message stating 'Value does not fall within the expected range' appears, often with a stack trace referencing Microsoft.Mashup.Client.Excel.
Ensure you have the latest Oracle ODBC or OLE DB drivers installed on your system. It is also recommended to back up your VBA script before making any connection string or code modifications.
Verify Connection Strings and Oracle Provider
The error often stems from incorrect connection properties or an incompatible Oracle provider specified in the VBA code.
A common cause of the 'Value does not fall within the expected range' error is an improperly formatted connection string or a missing OLE DB provider. Validating the parameters passed to the ADODB.Connection object is the best first step.
Press Alt + F11 in Excel to open the Visual Basic for Applications editor.
Find the module or form containing the ADODB.Connection or database connection string.
Ensure your ConnectionString uses the correct syntax for your installed Oracle driver (e.g., Provider=OraOLEDB.Oracle). Validate that the user ID, password, and data source are accurate without extra spaces.
Address Power Query (Mashup Client) Conflicts
Since the error references Microsoft.Mashup.Client.Excel, it may be related to Power Query background updates clashing with VBA.
Seek Specialized VBA Support
If the issue persists, leveraging specialized developer communities can help identify deep code-level issues.

Frequently Asked Questions
Why does Excel VBA throw a 'Value does not fall within the expected range' error?
This error typically occurs when an invalid parameter is passed to a function or connection string in VBA, such as an incorrect server name, missing driver, or syntax error in the Oracle OLE DB provider string.
What does Microsoft.Mashup.Client.Excel mean in the error trace?
Microsoft.Mashup.Client.Excel is the underlying engine for Power Query (Get & Transform). If it appears in a VBA error trace, it usually indicates a conflict between a VBA script and an active Power Query background refresh or connection.
How can I test my Oracle connection outside of VBA?
You can test the connection by creating an ODBC Data Source in Windows via the ODBC Data Source Administrator tool, or by using Excel's built-in 'Get Data' feature from the Data tab to connect to the Oracle database natively.
Does WPS Office support VBA and macros?
Yes, WPS Office supports VBA and macros in certain premium editions or specific regional versions. You can run many standard Excel macros by opening your .xlsm file in a VBA-enabled version of WPS Spreadsheet.
