Lesson 1Using VBA macros for simple automation: record macros, edit module, safe execution, workbook events (Workbook_Open, Worksheet_Change)Automate repeated tasks with VBA macros, from recording to editing code in modules. Learn safe running practices, use workbook events like Workbook_Open and Worksheet_Change, and build reliable automation for updating and formatting tasks in your daily work.

Build buttons and simple macros to refresh multiple objects in order, handle errors, and ensure users always see current data for accurate Ghanaian reports.

Work with TEXT, DATE, EOMONTH, MONTH, YEAR, and formatting to create month labels, fiscal periods, and dynamic date-driven summaries for dashboards and regular reports in local businesses.

Track changes to data sources, keep a change log, and add clear notes so future users can understand refresh steps and dependencies in Ghanaian office setups.

Build nested logical expressions, handle errors well, and design strong lookup chains for complex reporting models suited to Ghanaian data needs.

Set naming standards, navigation aids, and separation of raw data, staging, and presentation layers for efficient local use.

Set up connections, apply transformation steps, merge and append tables, and load results into Excel models while keeping queries refreshable and well documented for Ghanaian teams.

Build dropdowns for monthly paste-in templates, restrict invalid entries, and design friendly messages that guide users while protecting formulas and structures in daily workflows.

Learn when to use each, how they affect performance, and how to design reusable calculations for consistent reporting across pivots in local settings.

Convert ranges to tables, use table names in formulas, and define named ranges that update automatically as data grows for better Ghanaian productivity.

Combine IF with lookup functions, and apply SWITCH and CHOOSE to simplify nested logic, making models easier to audit and adjust over time in office environments.
