How to Fix Excel VBA Syntax or Compile Errors with Line Continuations
Question details
The user is experiencing syntax or compile errors when running an Excel VBA macro due to incorrectly formatted line continuations.
- Product
- Excel VBA
- Device & OS
- not provided
- Scenario
- Running or compiling a VBA macro where long lines of code have been broken into multiple lines for readability.
- Observed behavior
- The macro throws a compile or syntax error during execution. The code may work on one machine but fail on another because the continued lines are missing the required space and underscore, or because blank lines were inserted between the broken lines.
Before modifying your VBA code, press ALT + F11 to open the Visual Basic Editor and locate the specific line of code highlighted in red or yellow where the compile error occurs.
Correct the Space and Underscore Syntax
Ensure all broken VBA code lines properly use a space followed by an underscore to indicate a continuous statement.
In VBA, you cannot simply press Enter to move a long statement to the next line. You must explicitly tell the compiler that the statement continues by using a specific character sequence.
A common mistake is forgetting the space before the underscore, leaving trailing spaces after it, or adding empty lines in the middle of a continued block.
Press ALT + F11 to open the Visual Basic Editor and double-click your module in the Project Explorer to view the code.
Find the lines of code causing the syntax error, which are typically highlighted in red.
At the very end of the first line that is supposed to continue, type a single space followed by an underscore ( _ ).
Ensure there are no blank lines or comments inserted between the lines that form the single continued VBA statement.
Simplify Code by Using Explicit Ranges
Reduce the need for excessively long line continuations by utilizing explicit ranges instead of chaining ActiveCell and Selection methods.

Frequently Asked Questions
Why does my VBA macro work on one computer but throw a compile error on another?
This can happen due to differences in Excel compiler versions or regional settings. Older versions might be stricter about syntax, such as trailing spaces after a line continuation underscore, which newer versions might sometimes overlook or autocorrect.
What is the maximum number of line continuations allowed in a VBA statement?
In VBA, you can continue a single logical statement across a maximum of 25 physical lines using the space and underscore ( _ ) syntax. If you exceed this limit, the editor will generate a compile error.
Can I place a comment at the end of a continued VBA line?
No, you cannot place an inline comment (using an apostrophe) on the same line after a line continuation underscore. The compiler expects the next line to be the continuation of the code. Comments must be placed either before the statement begins or after the entire continued statement is finished.
How do I fix the 'Expected: expression' error when breaking a line?
The 'Expected: expression' error typically occurs if you split a string literal (text inside quotation marks) directly. To fix this, close the quotation marks on the first line, add an ampersand (&) to concatenate, and then add the space and underscore ( _ ) to continue the string on the next line.
