Leveling Up Data Analysis: How Automation, Power Query & Smart Strategies Can Transform Your Workflow

In an increasingly data-driven world, knowing how to efficiently collect, merge, and analyze information isn’t just a technical skill—it’s a strategic advantage. In our latest team session, we explored automating reports, mastering Power Query in Excel, and preparing for high-stakes interviews by showcasing data analysis expertise.

Here’s a recap of the essential insights—and why they matter if you want to stay ahead.

🚀 Automating Reports: From Manual to Magical

Nobody likes repetitive tasks, especially when the stakes are high. That’s why we kicked off by exploring how to automate daily, weekly, and monthly reports using Excel, OneDrive, and SharePoint integrations.

Key takeaways:

✅ Set automatic refresh timers so your reports always pull the latest data.
✅ Use append queries to combine multiple files in a folder into a single dataset.
✅ Build a date table to seamlessly link and organize reports over time.

👉 Why it matters: Automating reports frees you up to focus on insights, not tedious data prep.

🔗 Mastering Merges: Your Gateway to Smarter Data Connections

Next, we tackled the powerful (and often overlooked) world of merging data in Power Query. Using a tariff dataset example, we explored how to:

📝 Filter large datasets for specific conditions.
📝 Merge multiple sheets or tables to create unified reports.
📝 Understand merge types—inner join, left outer join, right outer join, full outer join, left anti join, right anti join.

Each merge type serves a purpose, like comparing sales data from 2024 and 2025 to find overlapping or unique customers.

👉 Pro tip: Always define your objective before choosing a merge type. Are you looking for matches, differences, or a complete view?

🏗️ Power Query in Action: Solving Real Problems

We dove into real-world troubleshooting as the team encountered issues with custom column formulas in Power Query. The solution?

💡 Leverage AI tools like ChatGPT to write or debug formulas.
💡 Pay close attention to case sensitivity and syntax.
💡 Use "Replace Values" to handle null entries gracefully.

The session wrapped with a live demo, showcasing practical fixes and reinforcing the mindset of iterative problem-solving.

🔍 Interview Prep: Proving Your Value Through Data Mastery

Beyond technical skills, the team discussed a critical career insight: solving urgent business problems = increasing your value.

For aspiring data analysts or anyone prepping for interviews:

✅ Focus on examples where you automated a process, saved time, or uncovered key insights.
✅ Prepare stories about how you used Power Query to merge, append, or transform data into actionable reports.
✅ Practice articulating the "why" behind your methods, not just the steps.

👉 Remember: Hiring managers want problem-solvers, not button-pushers.

📚 Looking Ahead: Case Studies & Continuous Learning

We closed the session with a commitment to deepen our learning:

📌 Load the next case study for hands-on practice.
📌 Attend the optional online class for tackling complex data analysis scenarios.
📌 Continue refining skills with merging, appending, and data modeling techniques.

Because data analytics isn’t a one-time skill—it’s a continuous journey.
