Microsoft fixes Excel’s copy-paste bug, but only for a small group of people

AI-summarised brief · reviewed before publication

Microsoft has released a targeted update that resolves a long‑standing copy‑paste malfunction in Excel, which caused certain cells to lose formatting or data when transferred between worksheets. The fix, rolled out through the Office Insider program, is currently available only to a limited cohort of users participating in the early‑access channel, while the broader public will receive the patch in a later cumulative update. The issue, first reported in early 2023, affected power users and enterprises that rely on complex spreadsheet operations, prompting work‑arounds that slowed productivity. Microsoft’s engineering team confirmed the root cause was a regression in the clipboard handling code introduced in a recent build, and the interim fix includes a rollback of the offending component. Full deployment is slated for the next quarterly update cycle.

💡 Why It Matters

  • · By addressing the bug now for insiders, Microsoft demonstrates a commitment to restoring trust among heavy Excel users before the fix reaches the wider audience, preventing further workflow disruptions.
