Défis Spreadsheets & Productivity Tools

Spreadsheets & Productivity Tools challenges put you inside the daily work of turning messy data into decisions. You'll develop skills in Microsoft Excel and Google Sheets, master Pivot Tables, VLOOKUP / XLOOKUP, INDEX / MATCH, and Conditional Formatting, and turn numbers into clear Chart Creation.

From there you'll handle the harder edges — Power Query, Multi-source modeling, Spreadsheet modeling, and Notion / Airtable databases — building Power BI / Looker / Tableau dashboards the way analysts actually do. Each challenge you solve earns a verified credential you can share with recruiters.
