[Help] How to create a formula for single data with multiple values?

Hello, I'm setting up a scenario to create a document with dynamic content.

THE SCENARIO
Step 1: Google Sheet - Watch New Rows

This Google Sheet contains columns with TRUE and FALSE values.

For example:

• Column 1: TRUE
• Column 2: FALSE
• Column 3: TRUE
• Column 4: TRUE
• etc.

Step 2: Google Sheet - Get Range Values

This Google Sheet is different from Step 1 and holds the corresponding values for columns marked as TRUE.

For example:

• Column 1: Lorem ipsum dolor sit amet, consectetur adipiscing elit.
• Column 2: Duis ut tortor in quam lobortis auctor.
• Column 3: Etiam eleifend mi ac mauris tincidunt vestibulum ut eget diam.
• Column 4: Suspendisse at finibus magna, eu dignissim quam.
• etc.

Step 3: Google Docs - Generate New Document From Template

This Google Sheet has a single variable named {{DYNAMIC_CONTENT}}.

THE GOAL

Given that the following columns in Step 1 are TRUE:

• COLUMN 1
• COLUMN 2
• COLUMN 4

The Google Docs output should resemble this, with proper spacing even when there are gaps for columns with FALSE values:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Etiam eleifend mi ac mauris tincidunt vestibulum ut eget diam. Suspendisse at finibus magna, eu dignissim quam.

PROBLEM

• Is there a more efficient method to generate the content than using a series of IF formulas?

Formula example:

IF(STEP1COLUMN1 = TRUE;STEP2COLUMN1;space)
IF(STEP1COLUMN2 = TRUE;STEP2COLUMN2;space)

This approach can become cumbersome with 20 or more columns. Additionally, there's an issue with generating excessive spaces if, for instance:

• Column 1 is TRUE
• Columns 2 through 24 are FALSE
• Column 25 is TRUE

This could result in 22 spaces.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. [_ this is the space I mentioned above _] Praesent scelerisque metus eu arcu finibus blandit.

Could you suggest a better way to handle this content generation?
