Power Query Consulting

Stop cleaning data manually. Automate it once.

Too many businesses spend hours every week doing the same thing... Pulling data from different places, cleaning it, reformatting it, and pasting it into a report that will be out of date before anyone reads it. Power Query eliminates that entirely.

At Office Experts Group, we build Power Query solutions that connect directly to your data sources and transform everything automatically on a schedule. Your reports are always current, always consistent, and no longer dependent on someone doing it by hand.

What We Build

Every Power Query solution, custom-built for your data.

Our clients come to us with a wide range of requirements that utilise Power Query. Be it simple connection and clean-up jobs through to multi-source ETL pipelines, M language custom functions, and Power BI dataflows. The right approach for each project depends on your data and your reporting requirements.

See our broader data manipulation services

ETL Pipeline Development

No-code · Scheduled refresh

We build automated extract-transform-load pipelines that pull data from your sources, clean and reshape it, then deliver it ready for analysis.

Capabilities
  • Connections to SQL Server, MySQL, PostgreSQL, Oracle, SharePoint, OneDrive
  • REST API and web service connectors
  • Automated refresh on a schedule or on demand
  • Deduplication, format standardisation, and column reshaping
  • Custom M language transformations for complex business logic
  • Error handling and refresh failure notifications

Data Cleansing & Transformation

Structured output · Repeatable steps

Inconsistent formatting, duplicate entries, split columns, and mismatched data types are the most common barriers to reliable reporting. We define and automate the steps that fix them.

Capabilities
  • Removing duplicates and handling nulls consistently
  • Splitting, merging, and reshaping columns
  • Standardising date formats, currency, and text casing
  • Unpivoting wide tables into analysis-ready structures
  • Conditional column logic and lookup enrichment

Multi-Source Data Merging

Append · Merge · Consolidate

When your data lives across multiple files, folders, or systems, We enable Power Query to merge and append them into a single table automatically.

Capabilities
  • Folder-level connectors that pick up new files automatically
  • Merge queries joining data across different sources
  • Appending data from multiple workbooks or databases
  • Handling schema changes and mismatched columns gracefully

M Language & Custom Functions

Advanced logic · Reusable

The graphical interface is fine for most situations, but complex business logic requires writing M directly. We author custom functions, parameters, and conditional logic that the UI cannot generate.

Capabilities
  • Custom reusable M functions for complex transformations
  • Dynamic parameters for date ranges, filters, and data sources
  • Incremental refresh configuration for large datasets
  • Query folding optimisation to push work back to the data source
  • Performance tuning for slow or resource-heavy queries

Power BI Integration

Excel · Power BI · Power Platform

Power Query is the data preparation layer for both Excel and Power BI. We build solutions that work across both, so your transformation logic is consistent no matter where the report lives.

Capabilities
  • Shared transformation logic across Excel and Power BI
  • Dataflow development for centralised, reusable query steps
  • Integration with Power Automate for triggered refreshes
  • Connection to Azure data sources and Microsoft Fabric
Choosing the right tool

Power Query or VBA? It depends on what you need.

Both tools solve data problems, but they do solve different ones. Understanding the differences helps you make the right decision. Our developers usually end up using both together.

Power Query
VBA / Macros
Best for
Power Query

Regular data refreshes, ETL pipelines, multi-source merging

VBA / Macros

Custom logic, UI interaction, file generation

Coding required
Power Query

No - M language optional for advanced scenarios

VBA / Macros

Yes - VBA scripting required

Refresh model
Power Query

Scheduled or one-click refresh

VBA / Macros

Triggered by macro or user action

Excel version
Power Query

Excel 2016+ and Microsoft 365

VBA / Macros

All Excel versions

Data source breadth
Power Query

Databases, APIs, SharePoint, web, files, cloud services

VBA / Macros

Files, databases via ADO/ODBC, Windows scripting

Maintenance
Power Query

Low - steps are visual and self-documenting

VBA / Macros

Higher - code requires developer knowledge to modify

When to use both

Most complex data automation projects use both tools. Power Query handles the data preparation and refresh while VBA handles everything that needs to happen once the data is ready.

  • Power Query shapes and loads the data; VBA automates what happens next
  • Complex file generation (PDFs, formatted reports) after a data refresh
  • User-triggered workflows that depend on clean, pre-processed data
  • Legacy macro systems being partially modernised

How We Work

From your first data source to a live automated solution.

Power Query projects can lead to failure not because the technology is wrong, but because the requirements were never fully understood before the build began. Thats why we start with a thorough analysis of your current system and future requirements.

Start a conversation

Built in your environment.

Every solution is developed inside your actual files, database connections, and SharePoint sites.

Architecture before build.

You see the full query design before a single step is written. Scope is fixed. There are no mid-project surprises.

Microsoft 365 specialists.

Power Query integrates with Excel, Power BI, Power Automate, and SharePoint. We cover the full Microsoft stack.

We stay after handover.

Data sources change. Source file formats evolve. Ongoing support if you need us in the future.

The four phases

  1. We start by understanding what data you have and where it lives. We find out your current manual steps, and the end reports or dashboards that depend on the output. The goal is a clear picture of what we can automate to make your life easier

Take it further

Pair Power Query with Power Pivot.

Power Query handles data extraction and transformation. Power Pivot then takes over with data modelling, DAX calculations, and the relationships that make dynamic dashboards and in-depth analysis possible. Together, they form a complete self-service data solution inside Excel or Power BI.
