The user needs to eliminate unwanted blank lines that appear when using hidden IF fields in a Word mail merge document.

How to Remove Blank Lines from Hidden Word Mail Merge Paragraphs

Product: Microsoft Word / WPS Writer
Device & OS: not provided
Scenario: Creating a mail merge document with conditional paragraph content controlled by IF fields.
Observed behavior: When the IF condition evaluates to false, the conditional text is hidden, but an empty blank line remains in the document because the paragraph mark was placed outside the IF field codes.

Before you start

Ensure you have your mail merge document open and toggle the field codes by pressing Alt+F9 so you can directly edit the structural syntax of your conditional fields.

Solution 1Recommended

Include the Paragraph Mark Inside the IF Field Condition

To prevent empty lines from appearing, the paragraph mark must be included as part of the true condition's output rather than sitting outside the field.

When creating conditional statements in a mail merge, any character placed outside the field codes, including paragraph returns, will be printed even if the field's result is empty. By encapsulating the paragraph mark inside the TRUE statement, the line break is only created when the condition is met.

Reveal Field Codes

Press Alt+F9 (or Option+F9 on Mac) to display the raw field codes in your document so you can edit the IF statement directly.

Locate the Conditional IF Field

Find the specific { IF } field that controls the conditional paragraph causing the blank line.

Move the Paragraph Mark

Ensure the entire text, including any nested merge fields and the paragraph mark (inserted by pressing Enter), is placed inside the quotation marks for the TRUE result. For example: { IF { MERGEFIELD Condition } = "Yes" "Your conditional text goes here.¶" "" }.

Set the FALSE Result to Empty

Make sure the FALSE result is simply an empty string, represented by empty quotation marks ("") directly after the TRUE result.

Update and Preview Results

Press Alt+F9 again to hide the field codes, then click 'Preview Results' on the Mailings tab to verify that the blank line completely disappears when the condition is not met.

Include the Paragraph Mark Inside the IF Field Condition

Handling Multiple Fields on One Line: If you have multiple IF fields on a single line, do not include paragraph marks inside the first few fields. Only include the paragraph mark for the final IF field that naturally concludes the line.

Frequently Asked Questions

Why does my mail merge document have blank lines even with the 'Don't print blank lines when data fields are empty' setting enabled?

That setting only applies to standard address blocks or single merge fields that are entirely empty. It does not automatically suppress paragraph marks left outside of complex conditional IF fields. You must manually include the paragraph mark inside the TRUE condition of the field code.

How do I see where my paragraph marks are located in the document?

You can reveal paragraph marks and other hidden formatting symbols by clicking the 'Show/Hide ¶' button on the Home tab, or by pressing Ctrl+Shift+8 (Command+8 on Mac).

Can I use multiple IF fields on the same line without creating blank lines?

Yes. When placing multiple IF fields on a single line, ensure that none of the TRUE results contain a paragraph mark, except for the very last field if you want the paragraph to end at that specific point.

How do I type the curly braces for field codes correctly?

Do not type the curly braces { } manually using the standard keyboard bracket keys. You must insert a blank field by pressing Ctrl+F9 (or Command+F9 on Mac), which creates the special field code braces recognized by the word processor.
