Why this program matters

  • Without advanced Power Query mastery, data teams waste 60% of their time on manual data cleaning, resulting in inaccurate reports that cost an average of 25 000€ per business incident.

  • Unoptimized companies see their ETLs balloon in duration, with 40% of queries failing on volumes >1M rows, directly impacting strategic decisions.

  • In 2024, 68% of BI recruiters reject profiles without advanced ETL skills, widening the competitive gap and risking market share losses.

  • Master Power Query to avoid these costly pitfalls.

Power Query training objectives

  • Master advanced M functions in Power Query for professional ETL
  • Develop parameterized and modular queries in a business context
  • Optimize performance for processing large volumes of data
  • Implement complex iterations and recursions with Power Query
  • Design certified ETL pipelines connected to Power BI
  • Automate data governance for sustainable skills

Power Query curriculum: 3 modules over 3 days

Module 1 : Advanced Power Query Transformations: M Functions and Complex Cleaning (Parameters, Iterations)

Dive into the M language to create custom functions, transform heterogeneous datasets from multiple sources like SQL Server or large CSV files, clean and structure non-normalized data via advanced conditional steps, perform practical exercises on real business cases with millions of rows, produce reusable queries and test their robustness for immediate efficiency gains.

Module 2 : Power Query Optimization: Performance and Modularity (Indexing, Buffering, Nested Tables)

Accelerate your ETL by mastering buffering and native indexing in Power Query, manage nested and hierarchical tables for multidimensional analyses, integrate dynamic parameters linked to Excel or Power BI, apply optimization techniques on massive datasets via collaborative practical workshops, diagnose bottlenecks with the built-in diagnostic tool, and deploy reusable modules that reduce processing time by 50% in production.

Module 3 : Power Query ETL Pipelines: Automation and Governance (Recursion, API, Enterprise Deployment)

Design recursive pipelines for iterative processing like accounting hierarchies, connect Power Query to secure REST APIs and real-time data streams, implement complete governance with logging and versioning, finalize a main project on a concrete business scenario such as financial consolidation, validate performance in real conditions, and prepare certified deployment for seamless integration into your enterprise BI tools.

How Power Query skills are assessed

  • Advanced multiple-choice quiz on M functions and optimization
  • Assessment via practical ETL projects
  • Presentation of the personalized main project pipeline

How the Power Query course is taught

  • Sessions led by active Power Query experts
  • Exercises on real and large enterprise datasets
  • Progressive 3-day main ETL project
  • Complete pedagogical support and M Language resources

Power Query training: access and practical arrangements

The Training Power Query - Automating ETL for Massive Data program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training Power Query - Automating ETL for Massive Data program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

Skills assessment methods

Assessment of skills acquired during the Training Power Query - Automating ETL for Massive Data program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

Our method

How Learni guarantees the quality of your Power Query training

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.

What can participants do after Power Query training?+
They can master advanced M functions in Power Query for professional ETL, develop parameterized and modular queries in a business context and optimize performance for processing large volumes of data. Those are the stated objectives of the Power Query program at Advanced level, checked by the end-of-session assessment.
What does the Power Query program cover, day by day?+
Day 1: Advanced Power Query Transformations: M Functions and Complex Cleaning (Parameters, Iterations). Day 2: Power Query Optimization: Performance and Modularity (Indexing, Buffering, Nested Tables). Day 3: Power Query ETL Pipelines: Automation and Governance (Recursion, API, Enterprise Deployment).
