Microsoft Excel for Data Analysis: A Practical Guide
Overview
A practical, hands-on guide that teaches how to use Microsoft Excel for cleaning, analyzing, visualizing, and summarizing data — from small spreadsheets to moderate-sized datasets. Focuses on real-world workflows, efficient formulas, built-in tools, and best practices to produce reliable results and compelling reports.
Who it’s for
- Analysts, managers, students, or anyone who works with tabular data.
- Users familiar with basic Excel who want to perform deeper analysis without switching to specialized software.
Key topics covered
-
Data import & setup
- Importing from CSV, TXT, and Excel files.
- Using Get & Transform (Power Query) to clean and reshape data: split columns, remove duplicates, change data types, merge/append queries.
- Best practices for raw data layout (one table per sheet, consistent headers, avoid merged cells).
-
Cleaning & transforming
- Text functions: LEFT, RIGHT, MID, TRIM, SUBSTITUTE.
- Date/time parsing and standardization.
- Conditional cleaning with IF, IFS, ISBLANK.
- Using Flash Fill and Find & Replace for quick fixes.
-
Formulas & functions for analysis
- Lookup and reference: VLOOKUP, INDEX+MATCH, XLOOKUP.
- Aggregation: SUMIFS, COUNTIFS, AVERAGEIFS.
- Dynamic arrays: FILTER, UNIQUE, SORT, SEQUENCE.
- Statistical functions: MEDIAN, STDEV.P, LARGE/SMALL.
- Logical & error-handling: AND, OR, IFERROR.
-
PivotTables
- Creating PivotTables from tables and data models.
- Grouping dates, calculating subtotals, using slicers.
- Calculated fields and value field settings.
- Best practices for updating and refreshing.
-
Data modeling & Power Pivot
- Creating relationships between tables.
- Introduction to DAX basics: SUMX, CALCULATE, RELATED.
- Handling larger datasets with the Data Model.
-
Visualization
- Choosing the right chart: column, line, bar, scatter, combo.
- Formatting tips for clarity: labels, axes, colors.
- Advanced visuals: Waterfall, Histogram, Box & Whisker, Map charts.
- Creating dashboards with interactive controls (slicers, timelines).
-
Automation & efficiency
- Named ranges and structured table references.
- Recording macros and basic VBA patterns for repetitive tasks.
- Using Power Query for repeatable ETL processes.
- Keyboard shortcuts and productivity tips.
-
Quality control & reproducibility
- Versioning and documentation within workbooks.
- Data validation rules and protection.
- Audit formulas with Trace Precedents/Dependents.
- Building reproducible analysis workflows.
-
Case studies & examples
- Sales performance dashboard.
- Customer churn analysis.
- Financial statement consolidation.
- Survey results summary with weights and segmentation.
