Excel guides, AI formula help and analysis
Excel is still where most analysis starts. These guides cover the parts that take the longest — formulas, cleaning, analysis structure and dashboards — and the free tools that shorten them.

Excel and AI: the parts that actually save time
AI helps most with the translation problems in Excel — intention to formula, error to cause, table to summary. It helps least with anything requiring knowledge of your business that you have not written down.
The Excel formula patterns worth knowing
Most spreadsheet requirements reduce to about eight formula patterns. Learn these and generated formulas become easy to verify.
A repeatable Excel data analysis process
Analysis goes wrong in predictable places: unchecked data quality, the wrong grain, and comparisons without a baseline. A fixed sequence prevents most of it.
Excel data cleaning checklist
Cleaning is not cosmetic. Most wrong analyses trace back to one of the six problems below.
How to analyse a CSV file
A CSV has no types, no formatting and no metadata. Everything you need to know has to be derived, which is exactly what a profiling pass does.
Excel dashboards that stay maintainable
The difference between a dashboard you can update in two minutes and one you dread is structural, and decided on day one.

- Import a CSV or XLSX file and keep working in a familiar grid
