How to Automatically Delete Empty Rows After a Word Mail Merge Using VBA
Question details
The user needs to automatically remove empty table rows or rows containing zero values after executing a mail merge.
- Product
- Word
- Device & OS
- not provided
- Scenario
- Performing a document mail merge where some source Excel data fields are empty or zero, which leaves unwanted blank rows in the final generated document's tables.
- Observed behavior
- The resulting merged document contains tables with empty rows or rows displaying a '0' due to missing or conditional data in the source file, requiring tedious manual cleanup.
Before running any VBA macros, ensure you have completed the mail merge to a new document and saved a backup copy. You will also need to enable the Developer tab in your word processor to access the VBA editor.
Run a VBA Macro to Delete Empty or Zero-Value Rows
Use a VBA script to iterate through the document's tables in reverse order, stripping end-of-cell markers and deleting rows that have no meaningful data.
Processing table rows from bottom to top is essential when deleting rows via VBA. If you loop from top to bottom, deleting a row shifts the remaining indexes upward, causing the macro to skip rows or throw an error.
This script strips the hidden end-of-cell markers (ASCII 13 and 7) native to Word tables to accurately check if the cell is truly empty or contains a '0' value.
With your merged document open, press 'ALT + F11' on your keyboard to launch the Microsoft Visual Basic for Applications (VBA) editor.
In the VBA editor, click on 'Insert' in the top menu bar, and then select 'Module' to create a blank workspace for your macro code.
Write a script that loops through 'ActiveDocument.Tables', and then nests a 'For... Step -1' loop to iterate backwards through 'Table.Rows'. Inside this loop, extract the text of the target cell, truncate the last two characters to remove cell markers, and check if the result is "" (empty) or "0".
Add an 'If' statement so that when the condition is met, the macro executes 'Row.Delete'. Close your loops with 'Next' statements.
Press 'F5' or click the green 'Run' arrow in the toolbar to execute the script. The empty rows in your merged document will be automatically removed.

Frequently Asked Questions
Why do I need to loop through table rows backwards in VBA?
When you delete a row, all subsequent rows shift up, changing their index numbers. If you loop forwards, the macro will skip the row immediately following a deleted row and may crash when it tries to access an index that no longer exists.
Can Mail Merge automatically suppress blank table rows without a macro?
While the standard Mail Merge feature can suppress blank lines (paragraphs) when a data field is empty, it does not automatically delete empty structural elements like table rows. A post-merge VBA macro is required to remove these rows completely.
How do I remove Word's end-of-cell markers in VBA before checking the text?
Word table cells contain hidden end-of-cell markers consisting of a Carriage Return and a Bell character (ASCII 13 and 7). You can remove them in VBA by truncating the last two characters of the text string using the formula `Left(CellText, Len(CellText) - 2)`.
