The Update Element Alt Text node sets or updates the alternative text (alt text) of elements in Google Slides presentations. Alt text serves as a unique identifier that other operations can use to target specific elements. This is an AI-powered node that can understand natural language instructions.

​
When to Use It

  • Label elements for identification in other operations
  • Set up elements for targeted updates and modifications
  • Organize presentation elements with meaningful names
  • Enable dynamic workflows that target specific elements
  • Improve accessibility of presentations
  • Create reusable presentation templates

​
Inputs

FieldTypeRequiredDescription
PresentationTextYesGoogle Slides presentation URL or ID
Element IDTextYesUnique identifier of the element to update
Alt TextTextYesNew alternative text for the element

​
Finding Element IDs

Use these operations to find element IDs:
  • Get Slide: Retrieve elements from a specific slide
  • List Elements: Get all elements across the presentation

​
Alt Text Best Practices

Use descriptive names:
  • revenue_chart for revenue charts
  • company_logo for logo images
  • summary_text for summary text boxes
  • kpi_table for KPI tables
Consistent naming:
  • Use underscores instead of spaces
  • Keep names short but descriptive
  • Use consistent prefixes (e.g., chart_, text_, image_)

​

Tips

Alt Text Strategy:
  • Set alt text immediately after creating elements
  • Use meaningful names that describe the element’s purpose
  • Follow naming conventions for consistency across presentations
  • Document your naming scheme for team workflows
Workflow Integration:
  • Always set alt text for elements you’ll modify later
  • Use descriptive names that make sense in your workflow context
  • Check existing alt text with Get Slide or List Elements first
  • Update alt text when repurposing elements for different content
