Sample data & practice files

Order-level sales rows with region, product, channel, units and revenue — the standard shape for pivot-table and SUMIFS practice.

An HR roster with department, job title, hire date, salary and city — for lookups, headcount reporting and date maths.

Monthly revenue, cost of goods, operating expense and headcount — a compact P&L base for margin, growth and CAGR work.

SKU-level stock with warehouse, quantity on hand, reorder point and unit cost — for conditional formatting and stock alerts.

Deliberately dirty rows — trailing spaces, mixed case, inconsistent dates and duplicate records — for data-cleaning practice.

Scores across five subjects per student — for AVERAGE, RANK, VLOOKUP grade bands and statistical practice.

Dated business expenses by category, department and payment status — for budget tracking and SUMIFS by month.

A CRM-shaped contact list with email, city, signup date and lifetime value — for merges, list comparison and text functions.

Tasks with owner, start and end dates, duration and percent complete — the input shape a Gantt chart needs.

Daily clock-in / clock-out entries with break minutes — for hour totals, overtime and time-format practice.
