The worksheet

Every extension on one sheet

One row per extension: source, version, ready for the target or not, and what you do with it. Dropdowns keep it fast, colours show the open work, and the summary counts itself.

  • Five tabs: start here, site, extensions, go-live, summary
  • Opens in Excel, LibreOffice and Google Sheets
  • The same list we need for a quote, if you want help later
