How to Make Alt Sequence Keys Work in Karabiner for Excel on Mac
People who remap their Mac with Karabiner-Elements almost always hit the same wall: they've got Ctrl → ⌘ working, but the Windows Alt Ribbon sequences — Alt, then H, O, I for AutoFit — still do nothing. Here's why, and how far you can actually get.
Quick answer: You can't, reliably. Karabiner can send a sequence of keystrokes from one trigger, but Windows Alt Ribbon sequences don't translate, because Excel for Mac has no Ribbon Access Key system for those keystrokes to drive — there's nothing listening. Menu-navigation workarounds (⌃F2, then arrow/letter keys) are fragile, version-sensitive, and must be hand-built per command. The tool that actually does this is MacCove's Mac Excel Shortcuts — it re-implements the Windows sequence model for Excel on Mac, and unlike a Karabiner setup there are no rules to write or maintain: install it and the sequences work.

Why the Windows Alt sequence doesn't port
On Windows, tapping and releasing Alt puts the Ribbon into Key Tips mode: every tab and button shows a letter, and you navigate by typing them. It's a stateful UI mode built into Office for Windows.
Excel for Mac has no equivalent mode. There is no "press a key to reveal Ribbon letters," so sending h then o then i after an Alt press goes nowhere, and Karabiner can't add a Ribbon navigation layer that the app doesn't provide.
What you can build in Karabiner
You can approximate a few commands by driving macOS menu-bar keyboard navigation instead of the Ribbon. macOS lets you focus the menu bar with ⌃F2 (or Fn+⌃F2), then move with arrow keys and type-ahead. A Karabiner rule can chain these keystrokes from a single trigger.
Why this is a poor substitute
Fragile: menu wording, order, and submenu depth change between Excel builds; a rule that works today can silently break after an update.
Timing-dependent: menu navigation needs delays between keystrokes.
One rule per command: you're hand-authoring and maintaining a rule for every sequence you used on Windows.
No Key Tips feedback: you can't see where you are mid-sequence like you could on Windows.
The practical split
Use Karabiner for: remapping the physical Ctrl key to ⌘ (optional), single-key and chord remaps, per-app modifier conditions
Use Mac Excel Shortcuts for: Windows Alt → letter → letter chains, Paste Special variants, AutoFit, Freeze Panes sequences, anything you want working across Excel updates without maintenance
For the chord shortcuts themselves you often need neither — the ⌘ equivalents already work in Excel for Mac.
FAQs
Can Karabiner-Elements do Windows Alt key sequences for Excel on Mac?
Not in the way they work on Windows. Excel for Mac has no Ribbon Access Key mode, so there's nothing for the keystrokes to control. You can only approximate a few commands by scripting macOS menu-bar navigation, which is fragile.
Is there a Karabiner rule file for Excel Ribbon shortcuts?
Community rule sets exist for Ctrl → ⌘ and function-key fixes. Full Windows Ribbon-sequence emulation isn't something Karabiner can deliver reliably.
What actually replicates Alt-key Ribbon sequences on Mac?
MacCove's Mac Excel Shortcuts is built for that model — it maps Windows-style step-by-step command paths onto real Mac Excel commands and keeps working across updates.
Should I use Karabiner at all then?
Only if you want the physical Ctrl key remapped to ⌘ and don't mind maintaining a config file — that's the one job it does well here. Most people press ⌘ by habit instead and skip it. Either way, the Ribbon sequences need Mac Excel Shortcuts, which installs with nothing to configure.
