Cellgrids teaches Excel the way it's actually used at work — real formulas, real corporate scenarios, real practice. Not another course that stops at theory.
Most Excel content either stays too basic to matter at work, or jumps into advanced tricks nobody explains properly. This platform was built to close that gap — real formulas, real corporate scenarios, and an actual spreadsheet to practice in, not a multiple-choice quiz. The goal is simple: get comfortable enough to open a blank sheet at work and actually build something.

Where Rinkesh is now
Cellgrids is a free Excel learning platform with practice, guides and paid courses. You can practise 500+ Excel formulas in a live spreadsheet that checks your answer, read step-by-step guides with real examples, work through business case studies, prepare for data and MIS interviews, and take structured Excel courses that end with a test and a certificate you can verify online.
Practice answers are checked by a spreadsheet engine before they go live, and guides are written around real office tasks such as MIS reports, sales summaries and payroll sheets. We update pages when Excel changes, and we fix mistakes quickly when readers report them through the Contact page.
Beginners who want to start Excel properly, office staff who build reports every week, job seekers preparing for Excel and analyst interviews, and analysts who want to move into Power Query, Power Pivot and dashboards.
