How it works
One workbook. Three clear steps.
- 1
Open your workbook
Download the workbook, open it in Microsoft Excel or another compatible spreadsheet application, complete the highlighted task, and save the finished file as .xlsx. The original stays unchanged.
- 2
Complete the analysis
Repair data and formulas, calculate the requested metrics, document validation, and write the recommendation.
- 3
Submit and receive feedback
Upload the finished .xlsx for diagnostic feedback. A passing result receives a short changed-requirement task, then a structurally changed challenge 48 hours later. A task record is issued only if the required sections pass; otherwise the result stays private.
AI and normal online resources are allowed. You remain responsible for checking the work and disclosing how tools were used.

Your alias appears only on a proof record if you pass. Feedback is available on this page; an email is optional and used only for participant updates.
Use fictional data only. Do not enter employer, client, customer, identity-document, or sensitive information.
Clear limits
A task record, not a broad credential
The record represents performance on specific disclosed spreadsheet tasks under self-reported tool-use conditions. AI and online resources are allowed when disclosed. It does not establish independent authorship, mastery, certification, professional experience, employability, or future performance.
