Today's Goals
- Self-check six core Excel skills
- Finish one mixed mini-exercise end to end
- Know what to learn next and which course to open
Key Concepts
1. What comes after the basics
Five lessons built five skills: formulas and addresses, common functions, VLOOKUP, pivot tables, conditional formatting. The sixth is the habit that binds them inside one workbook — clean data. Messy sources break reports no matter how many functions you know; with clean sources, all six skills click together. The check counts these six, not how many functions you can recite.
2. The six-skill checklist
- Clean data: one record per row, no merged header cells
- Formulas: arithmetic plus how addresses drift when dragged
- Functions: SUM/AVERAGE/MAX/MIN/COUNT from memory
- Lookup: four VLOOKUP arguments on demand; check formats first when #N/A appears
- Aggregation: 3000 rows summarized in five minutes
- Alarms: whole-row conditional formatting, $E2 locked correctly
Stuck on one? Go back to that lesson only.
3. The one insight that matters
Beginner formulas live in plain sight — visible and traceable. Real projects are the same six skills rearranged by business logic: a stock ledger is clean flow records + VLOOKUP on the item file + summary functions + conditional-format alerts. Skills constant, arrangement new. That is the honest relationship between basics and projects.
Today's Code
Mixed exercise: a 20-row sales detail (date / rep / region / product / price / qty), six tasks:
| Task | Skill | Reference |
|---|---|---|
| Amount per row | Formula | =E2*F2, drag down |
| Total and average | Functions | =SUM / =AVERAGE |
| Category per product | Lookup | =VLOOKUP(D2,CatTable,2,FALSE) |
| Sales per region | Aggregation | Pivot: Rows=Region, Values=Amount |
| Highlight top five | Alarms | Conditional format: greater than the 5th highest |
| Audit the source | Clean data | No merges, no blank rows, real dates |
Every task verifies on its own: spot-check two rows of task 3; task 4's grand total must equal task 2's — two different tools agreeing on one number is the hard self-check.
Exercises
- Finish all six tasks, timed; target: 30 minutes.
- Turn one price into text on purpose; watch tasks 1, 2 and 4, then repair the damage.
- Add Rep as a pivot column; verify the region totals still match task 2.
Exercise Solutions
- Suggested order: clean first (task 6), then amounts, functions, lookup, pivot, colors — reversing the order means rework.
- The sum shrinks or returns 0; the pivot counts instead of sums. Fix: select the column → Data → Text to Columns → Finish, or use the green-triangle converter.
- Column totals should add up to the grand total; if not, text numbers or duplicate rows remain in the source.
Real-World Scenario
The question after lesson six is always "which project next?" The paths are ready-made: stock control in the Inventory course (18 lessons, from one sheet to a traceable system); trading in the Purchase-Sales course (24 lessons: files, flows, pivots, dashboards); customers in the CRM course (20 lessons, leads to payments, with VBA automation late on). All three assume exactly these six skills and open with business modeling. Basics teach skills; projects teach combinations. When a project lesson gets hard, one of the six is usually shaky — come back and patch just that one.
Common Errors and Troubleshooting
The errors scattered across lessons 1–5, gathered into one master checklist:
| Symptom | Likely cause | Back to |
|---|---|---|
| #NAME? | Misspelled function / full-width punctuation | Lesson 2 |
| #N/A | Format mismatch / hidden spaces | Lesson 3 |
| #REF! | VLOOKUP column index out of range | Lesson 3 |
| #DIV/0! | No numbers in the AVERAGE range | Lesson 2 |
| Invalid field name (pivot) | Blank headers / merged cells | Lesson 4 |
| Whole block colors | $ locked the row too | Lesson 5 |
| Sum stays 0 | Numbers stored as text | Lesson 2 |
Extension Exercises
- Redo all six tasks on real data from your own job — none skipped.
- Add a "Notes" column full of stray text, re-run the pivot, and feel how a dirty field interferes; practice cleaning it.
Summary
The path closes here: formulas, functions, lookup, pivots, alarms, clean data. Pass the six-skill check and the three project courses are open to you. The bar is simple — six for six within 30 minutes, and you are no longer a beginner.
