We've obviously received feedback from some of you that the Excel macro doesn't meet your needs or expectations. There are some known issues with it right now that impact the display of spreadsheets.
You may legitimately ask, why did we proceed with the rollout when these known issues exist? We're making infrastructure changes for the overall benefit of Confluence Cloud users, but they mean that we can't keep the old Office and PDF macros working any longer. We need to proceed with this rollout so we can move forward with the infrastructure changes, which have a much wider impact than this macro.
In saying that, we, of course, genuinely care about every user's experience with Confluence, and always want it to be the best. We really regret any negative consequences this release has caused, and realize that any explanation of trade-offs will be of little comfort when you rely on this macro's functionality.
There unfortunately isn't a short-term fix for this issue, but we're investigating a better long-term solution for Excel and other Office files, and we'll update you when we have news to share.
