How it connects
Microsoft Excel has an official connector in Claude's directory. A Claude admin switches it on and each person signs in with their own Microsoft Excel login, so Claude only sees what they're allowed to see. Helm handles the setup, checks the permissions and trains your team on what to ask.
Looking after your Microsoft Excel data
Workbooks can hold anything from payroll to client pricing, so Helm limits Claude to the specific files and folders your team names and has it report every cell it changes.
- Only the access you approve.
- Everything stays in your own accounts.
- On Claude's business plans, your data isn't used to train AI models.
