Marimo: Create your own data applications without coding

Stop constantly editing Excel. Instead, create your own data tools.

Stop endlessly tweaking Excel. Create your own data tools. Quickly and without complicated coding. Training is led by experienced instructors with years of practical experience across various industries. We focus on practical application — no unnecessary theory.

Who is this course for

Typically:

  • Analysts (data, business, reporting)
  • Marketers (PPC, e-commerce, performance)
  • Product managers
  • Finance and controlling
  • Operations roles

This is for you if:

  • You spend a lot of time in Excel
  • You perform repetitive analyses or generate reports
  • You want to work with larger datasets without slowing down
  • You’re looking for a way to simplify and automate your work
  • You don’t want to be dependent on developers

Basic knowledge of Excel (formulas, filters, pivot tables) is sufficient. Knowledge of SQL is a plus; Python is not required.

Do you work with data in Excel?

Then you’re probably familiar with this:

  • The same analyses over and over again
  • Large files that keep getting slower
  • Complicated sharing with colleagues
  • Dependence on someone who “knows how to code”

Marimo is the next logical step. You’ll keep working with the data you know. You’ll just make it significantly easier.

What You’ll Gain from the Course

By the end of the course, you’ll be able to:

  • Create your own simple data applications
  • Replace repetitive work in Excel with simple automation
  • Work with larger datasets without slowing down
  • Share clear, interactive outputs
  • You won’t be dependent on programmers

A Major Advantage: AI Assistants

You don’t have to memorize syntax or worry about the details.

We’ll show you how to use AI assistants in marimo to help you:

  • Write SQL queries
  • Edit and analyze data
  • Generate and explain code
  • Build entire sections of the application

This makes the course accessible even to beginners.
