I'm having issues copying certain graphs from Excel to Illustrator. Some paste just fine. Others paste like this example. The text is scrambled. I'm assuming it's a security measure encrypting the data. Wanted to ask the community though as this isn't always the case.
Is that on a Mac?
In that case try a different font in Excel. There maight be issues with Calibri
Lol I was not expecting this but this solved my issue. Directly copy-pasting an excel table with Calibri text led to a table full of nonsense pasted into illustrator. Changed the font in excel & problem solved! This is such a weird bug 😄
