Logo Link URLs return images directly, so you can embed company logos in Excel with the IMAGE() function — no code required. Logo Link in Microsoft Excel
The IMAGE() function requires Excel for Microsoft 365 or Excel for the web. It is not available in older desktop versions of Excel.

​
Basic Usage

Use the IMAGE() function with a Logo Link URL: 
=IMAGE("https://logos.context.dev/?publicClientId=brandLL_xxx&domain=github.com")
Get your API key from the Context.dev dashboard to get started.

​
Dynamic Domains

Reference a cell containing the domain instead of hardcoding it. If cell A2 contains github.com: 
=IMAGE("https://logos.context.dev/?publicClientId=brandLL_xxx&domain=" & A2)
Drag the formula down a column to fetch logos for an entire list of domains.

​
Sizing

Pass optional sizing parameters to control how the logo displays: 
=IMAGE("https://logos.context.dev/?publicClientId=brandLL_xxx&domain=github.com", "GitHub logo", 1)
The third parameter sets the sizing mode: 0 for fit to cell (default) or 1 for fill the cell.
Adjust row height and column width so logos display at a reasonable size.

​
Fallbacks

If a logo isn’t found for a domain, Logo Link automatically returns a generated monogram — cells will never show a broken image.
