Create and safely revise Excel workbooks

Updated 2026-07-13·3 min read

How Aimee creates K3-styled workbooks, inspects existing files, and makes copy-first Excel changes.


Creating a workbook

Ask Aimee for a spreadsheet and describe the sheets, columns, formulas and number formats you need. New K3 workbooks use Aptos, Teal headers, Ink text and Ice Blue input cells by default.

Safe revisions

  1. Attach or identify the workbook and ask Aimee to inspect it first.
  2. Describe the exact cells or structural change required.
  3. Aimee creates a new version or copy and leaves the source workbook unchanged.
  4. Open the result in the read-only viewer and verify formulas, charts and assumptions before final use.

If a requested structural edit cannot preserve the source workbook, Aimee should say so rather than presenting a reconstructed workbook as an edit.
