Learn to solve any business modeling task you might ever experience! Have you ever felt that you’re regularly repeating some tasks in Google Sheets or Excel? Have you ever thought about the time you would save if you would automate those tasks?

All the work you’re doing in a repetitive manner in Google Sheets or Excel could be automated. And that’s where I can help. I’m the Director of Business Analytics at European fastest growing technology firm Bolt, where I’m standing just in the middle of tech and business people. And as you might know, business people love spreadsheets. Simply because they are so easy to use, you can do so many ad-hoc analyses there, and it’s purely a common-sense tool to use.

But that doesn’t mean that people know how to use it right. People often use clunky formulas and esthetically unappealing formatting practices, which doesn’t make the dashboards and files the most user-friendly to use. Moreover, when something is not visually and technically working as effectively as it could, it slows down every user from focusing on things that matter and that results often in lower quality of work — with absolutely no good reason for that.

Hence, I’m a pure advocate of well-looking and fully automated spreadsheets that require a minimal amount of manual effort and can easily be scaled to hundreds of different files used by thousands of people daily. All this involves a combination of highly complex formulas, effective data visualisation, mathematical thinking and often syncing your spreadsheets with scripts such as Python or Google Apps Script.

And that’s why I have created this course. I’ve worked with spreadsheets for a long time and always have got amazing feedback from all the people who’ve been using dashboards and tools built by me. So one day, I decided that instead of only producing dashboards for other people, I’d rather teach them how to do ones themselves. And that’s why I have created this course. To give all my core knowledge over to you, so you can become more effective in what you do, and continue building on top of this knowledge even further.

It’s all up to you, eventually. But what I can offer is 6.5 hours of highly valuable content, packed to an online course using the skills that I’d want to pass over to you.



This course is already changing lives… will you be next?

I’ve taken several online courses, some of which were fantastic, but this is the first course (I believe) that is so good that I feel compelled to leave a review. I’m a web developer with interest in Google Workspace automation. I’ve always preferred to do all the automation in Apps Script, but some of my clients asked for solutions using Google formulas. This course is excellent in going super-deep and hands-on on automating reporting. The instructor clearly has deep industry experience in not only the technical aspects of automating reports that business executives consume, but also in how to handle a spreadsheet effectively and efficiently. So it’s not just about mastering the formulas but also about how to operate the spreadsheet and its data. I recommend this course wholeheartedly.

This is one of the extraordinary online courses I have ever undergone. The instructor is purely straight to the point and makes it very easier to understand. So far I completed almost 25% of it and “use of dollar sign” “IFERROR” , “INDEX and MATCH”, “TRANSPOSE”, “IMPORTRANGE’ are great learnings and life savings. Thanks to the instructor for putting such effort. I highly recommend this course for those who want to get the most out of Google Sheets.

The course is FANTASTIC! First, it is clear that Mariel knows the topic. She is a real professional and it becomes clear as we progress in the course. I have used Excel for 21 years. I am still a heavy user. However I was made aware of the great use of query function within Google Sheets a while ago and started to understand the power of Google Sheets. This course may not be perfect for beginners, however, for intermediate and advanced users, it is FANTASTIC. Thanks Mariel for the amazing course. I really enjoyed your teaching style and your expertise. What a treat! Thanks.
