Security & Privacy

  • Data sovereignty

    I never see your data. The script runs entirely within your Google environment.

  • Code ownership

    You own the source code. No hidden backdoors or obfuscated logic.

  • Zero-access policy

    Limited-scope permissions—I only see what is necessary to build the tool.

The Problem

Desktop-locked Excel files, "Read-Only" errors, and broken macros on Mac or mobile. Your business logic is trapped in a single file, and your team can't collaborate in real time. When someone leaves, the macros often leave with them.

You need your processes in the cloud, without rewriting everything from scratch.

The Solution

I convert your complex VBA modules into high-performance JavaScript (Apps Script). Your logic moves into Google Sheets and Google Workspace, same business rules, modern infrastructure. No more file versioning hell or "only works on my machine."

  • Multi-user collaboration: Everyone works in the same sheet, in real time.
  • Automated cloud triggers: No more clicking "Run." Scripts run on a schedule or when data changes.
  • Cross-device compatibility: Works on Mac, Windows, and mobile. One source of truth in the cloud.

What You Get

  • VBA logic translated to clean, documented Apps Script.
  • Time- and event-based triggers so automation runs without you.
  • Sheets that behave like your Excel workbook, with cloud superpowers.

Why Apps Script vs alternatives

Zapier and Make are great for quick connects. Custom Apps Script wins when logic, ownership, and Workspace depth matter.
