Data lands in spreadsheets first. A sharp Excel user turns mess into insight—and does it quickly.

How to Improve Excel Skills

Aim for speed and reliability:

1. Shortcuts and navigation: Cut mouse time; learn selection tricks and quick fills.
2. Functions that matter: IF, INDEX, MATCH, XLOOKUP, SUMIFS, TEXTSPLIT, FILTER, LET, LAMBDA.
3. PivotTables and PivotCharts: Summarize, slice, drill down without fragile formulas.
4. Data shaping: Clean and combine with Power Query; validate inputs to prevent errors.
5. Visualization: Choose clear chart types, add sparklines, tell the story.
6. Quality and audit: Named ranges, structured references, and checks that catch mistakes.
7. Stay updated: New dynamic arrays and functions roll out often; learn them.
