0000 demo workbooks · Copilot in Excel companion
https://copilotinexel.jardenberg.net/

Three synthetic Excel files from my Copilot demonstrations. Use them to rehearse
the moves on the site before you turn to your own data. Your own workbooks are
the point; these are the sandbox.

  0000 Claims.xlsx                      145 warranty claims (sheet: Claims)
  0000 Support_Cases.xlsx               280 support cases (sheet: Support Cases)
  0000 Full_warranty_and_goodwill.xlsx  481 time entries (sheet: Warranty & Goodwill)

The data is invented. "NovaTech" and its subsidiaries do not exist. The customer
names in the Account column are well-known companies used as placeholders; none
of the cases, parts or work orders are real. Nothing here comes from Mycronic or
from any client system.

How I use them: save the three files to your OneDrive, open Copilot Chat, type a
slash and pick them (or just ask Copilot to find the files that begin with 0000),
then try "What are examples of insights that I could get from these three files?"
A good number to check: the Claims file holds exactly 145 claims.
