Merge JSON data with PowerPoint template

Placeholder Syntax

• Text Values: Use double curly braces for text placeholders. Example: {{name}}, {{company}}, {{title}}
• Image URLs: Use the same format as for text placeholders, but place them in the Alt-text field of the image. Example: {{profile_picture}}, {{company_logo}}.
  You must add sample image (it will be replaced with the one under the provided URL) and type the placeholder name into the contents of "Alt text". This can be achieved by right-clicking the image and selecting "Show alt text" from the menu.
• QR Codes: QR codes are special components for which you point to the data to be encoded in the QR code. Example: {{data=contact_info type=qr}}, {{ data=website_url type=qr }}.
  You must add a sample image (the one to be replaced with generated QR code) and type the placeholder name into the contents of "Alt text". This can be achieved by right-clicking the image and selecting "Show alt text" from the menu.
