Why this program matters

  • Without intermediate Power Query mastery, data analysts lose 50% of their time on repetitive manual tasks, generating up to 20 000€ in annual per-position costs from data errors.

  • Non-optimized companies incur 30% monthly reporting incidents from failing ETL processes, undermining strategic decisions.

  • In 2024, 65% of BI job postings require Power Query, excluding unqualified candidates and blocking internal promotions.

  • Every quarter without training widens a fatal competitive gap against agile teams that automate in hours what you do in days.

Power Query training objectives

  • Master advanced Power Query functions for professional ETL
  • Develop parameterized and reusable queries for enterprise use
  • Optimize performance for processing large volumes of data
  • Implement complex joins and conditional transformations
  • Design certified ETL pipelines connected to Power BI
  • Automate extraction and cleaning from multiple data sources

Power Query curriculum: 4 modules over 4 days

Module 1 : Advanced Power Query Transformations: Custom Functions and Cleaning (M Language, Advanced Editor)

Dive into the Power Query editor to create custom functions in M Language, clean complex datasets from CSV and SQL sources, apply conditional transformations on millions of rows, perform practical exercises on real enterprise cases such as monthly sales consolidation, produce a first reusable ETL pipeline with dynamic parameterization, and validate your skills through immediate performance auditing.

Module 2 : Power Query Joins and Aggregations: Data Modeling (Linked Tables, DAX Intro, Grouping)

Master advanced joins between heterogeneous sources like Excel, web, and databases, aggregate data with custom groupings and hierarchical calculations, integrate an introduction to DAX for dynamic measures, work on a concrete multi-source financial reporting case, generate optimized pivot tables ready for Power BI, and optimize memory usage through buffering techniques, while documenting your queries for team maintenance.

Module 3 : Power Query Parameterization and Automation: Loops and APIs (Parameters, Iterative Scripts, REST Flows)

Set up parameterized queries for maximum flexibility in production, implement recursive loops to handle nested structures like JSON/API, connect Power Query to real-time web services, develop an automated script extracting daily e-commerce data, test robustness on real error scenarios, produce a deliverable ETL dashboard with error logging, and measure time savings for your business processes.

Module 4 : Power Query Optimization and Deployment: Performance and Integration (Debugging, Power BI Service, Governance)

Optimize query performance on large volumes with indexing and native folding, debug complex pipelines using the advanced traceability tool, integrate your ETL into Power BI Service for enterprise deployment, complete an end-to-end project on anonymized HR data, evaluate performance metrics before/after, prepare certified data governance, and leave with a professional starter kit including templates and best practices.

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.
