Legacy Excel is a single point of failure
When the "macro person" leaves — or the laptop dies — the process stops. Cloud migration is not about shiny tech; it is about business continuity.
- Single-PC dependency: Macros only run where Excel and the right add-ins live.
- Version chaos: Emailing workbooks creates conflicting truths.
- No mobile path: Field or remote staff cannot run critical automation.
- Manual "Run": Nobody remembers to click the button at 8am.
If the workbook runs the business, it belongs in Workspace — with triggers that fire without you.
Start with a free feasibility study
Share your Excel (or describe the macros). I tell you what migrates cleanly, what needs redesign, and a realistic timeline — before you commit budget.
Upload Workbook for ReviewWhat a migration includes
Not a blind line-by-line dump — a cloud-ready redesign that keeps your rules and drops the desktop constraints.
- 01 · AuditClear go / no-go before you spend
Feasibility study on your workbook
Upload your Excel/VBA. I map which macros translate cleanly, which need redesign, and what cloud triggers replace Workbook_Open clicks.

VBA → Apps Script translation
Business rules preserved as clean JavaScript: calculations, approvals, PDF generation, and report packs — documented for your team.

Multi-user Sheets redesign
Structure tabs and permissions for simultaneous editors — no more emailing file_v27_FINAL.xlsx or Read-Only collisions.

Replace desktop-only Run macros with time-driven and installable triggers that work when nobody is at the PC.

Honest about the 5% that does not port
Most calculation and sheet logic ports cleanly. Local file-system access, ActiveX, and VBA UserForms do not — we replace them with Drive triggers, HtmlService UIs, or sidebars that are usually better for users.
- Formula mapping: Excel → Sheets equivalents documented (QUERY, XLOOKUP, locales).
- Quota-aware design: Batching for large workbooks under Apps Script limits.
- Team handover: Comments, runbook, and walkthrough so knowledge is not trapped again.
From workbook review to live Sheets in four steps
- Free feasibility study: Macro inventory, risks, and recommended approach.
- Scope & quote (within 24 hours): Fixed-scope quote with milestones.
- Translate & redesign: Logic + sheet structure + triggers in a sandbox.
- Cutover & handoff: Parallel run if needed, then docs and training.
Why teams hire AppScriptExpert for VBA migration
I have moved quote engines, reporting packs, and inventory macros off fragile desktops into Workspace — with attention to what must stay identical and what should improve. Need ongoing Sheets automation after migration? See Google Sheets automation.
