Google Sheets

Start with a known file key

Put AAPL in A2, then enter this in B2:

=IMAGE("https://img.brandmarks.dev/logos/v1/email/mark-128/"&A2&".png",1)

Mode 1 fits the image within the cell while keeping its proportions. Increase row height and column width, then fill down for other verified file keys. These are storage keys, not arbitrary names or API identifiers: for example, use BRK.B for the static share-class file, not BRK-B.

For mixed ticker spellings, prepare a lookup table from the manifest first. If a company has no distinct mark, use its full-logo PNG instead.

Troubleshooting

Use PNG; Google Sheets IMAGE does not support SVG. Open the generated URL to check for a missing file. A company name in A2 will not automatically resolve. Keep company text in a neighboring column and never put a secret API key in a shared sheet.

This is a formula integration, not an installed Brandmarks add-on. See Google’s IMAGE reference for application restrictions.
