Search Methods: How to Find Text

​
Regular Text Mode

Finds text by its actual visible content.
  • Use for: One-time styling, simple formatting changes
  • Example: Style “Total Revenue: $50,000” by searching for that exact text

​
Alt Text Mode

Uses hidden alt text labels to identify text elements.
  • Use for: Recurring reports, reusable templates
  • Example: Label a text box “revenue_highlight” and style it repeatedly
What is Alt Text? A hidden label you add to text elements. Right-click → Alt text to set descriptive names like “key_metric” or “header_title”.

​
Text Selection Methods: Manual vs Structured Data (Bulk)

​
Manual Selection

Style individual text elements one by one. Best for:
  • 1-5 text elements
  • Simple formatting updates
  • One-off presentation styling
Example:
  • Style “Q4 Results” as bold, size 24
  • Style “$125,000” in red color

​
Structured Data (Bulk)

Apply different styles to multiple text elements using data from previous workflow steps. Best for:
  • 10+ text elements
  • Dynamic styling based on data
  • Automated report formatting
Example: Style positive numbers in green, negative in red automatically.

​
Examples

​
Manual Styling Example

Scenario: Highlight key metrics in a quarterly report Setup:
  • Set alt text “revenue_number” on revenue figure
  • Set alt text “growth_rate” on percentage
  • Set alt text “main_title” on presentation title
Styling:
  • revenue_number: Bold, size 20, green color
  • growth_rate: Bold, red color (if negative)
  • main_title: Size 28, blue color

​
Structured Data (Bulk) Example

Scenario: Automatically format percentage changes based on performance Workflow:
  1. Get Report from Google Ads with current and previous month data
  2. AI Generate Structured Output to calculate percentage changes and assign colors
  3. Update Text Style to apply green/red formatting automatically
AI Structured Output generates:
