NovaExcel teaches Excel VBA the way people actually learn it: by reading working code, understanding every line, and running it themselves. Twenty courses take you from your first recorded macro to class modules, ADO and web APIs. Every lesson ends with a knowledge check and every course ends with an exam; pass it and you can create a PDF certificate of completion with your name. WHAT YOU LEARN • VBA Basics — the editor, modules, variables, your first working macro • Ranges & Cells — address the right cells without ever clicking • Logic & Loops — decisions and repetition across thousands of rows • Macro Recorder & Cleanup — record, read, then rewrite into something fast • Worksheets & Workbooks — the right sheet in the right file, every time • Errors & Debugging — break mode, the watch window, error handlers that help • UserForms — real dialogs with controls and validation • Automation & Reports — events, scheduled work, finished reports • Arrays & Performance — why cell-by-cell loops crawl and arrays fly • Collections & Dictionary — keyed storage, grouping, de-duplication • Text & Strings — cutting, cleaning and parsing text • Dates & Times — serial numbers, formats and the traps • UDFs — your own worksheet functions • PivotTables in VBA — build, refresh and filter from code • Charts in VBA — ChartObjects, series and export • Tables & ListObjects — structured references done right • Files & Folders — paths, existence checks, reading and writing • SQL & ADO — query a workbook like a database (Windows) • Web & APIs — HTTP requests and JSON in VBA, with the honest limits • Class Modules — properties, methods and code that stays maintainable HOW IT WORKS Premium: pay once, no subscription. All 20 courses, 151 lessons and all 20 final exams are unlocked from the first launch. All content is stored in the app, so it works fully offline. No account, no sign-in: your progress, exam results and certificates stay on your device. HONEST ABOUT LIMITS This app teaches VBA — it does not run VBA. You write and run the code in Excel on your Mac or PC; the app is where you learn what to write and why. Where something is Windows-only (Scripting.Dictionary, FileSystemObject, ADO), the lessons say so instead of pretending otherwise. Exams are graded in the app, on your device. The certificate you can create (as a PDF, with your name) is a self-study certificate of completion from NovaExcel, not an accredited qualification. NovaExcel is an independent training product. It is not affiliated with, endorsed by, or certified by Microsoft. Microsoft and Excel are trademarks of Microsoft Corporation.
