Data & ETL Services
Practical data transformation, migration, validation and automation services from the team behind Advanced ETL Processor.
Data services from ETL Tools are hands-on engineering work for organisations that need help moving, transforming, validating, integrating or automating data. We are not a general management consultancy. We build the workflow, test the output and explain what happens when a CSV file decides to develop a personality.

ETL services for real data problems, not slide decks
ETL Tools provides technical services for one-off data migrations, difficult legacy conversions, recurring ETL processes, Excel automation, data quality projects, complex NHS and healthcare data processing, and reusable automated workflows.
In many projects, the result is a maintainable Advanced ETL Processor workflow that the customer can keep running themselves. That matters when the same data arrives next month wearing a slightly different hat.

Typical projects
The work usually starts with a business problem
Technology matters, but the real question is usually simpler: what data do you have, where must it go, what rules must it follow, and how often will the job repeat?
How we work
A good data project is tested before anyone trusts it
We start with the problem and sample data, then turn the rules into a workflow that can be tested, reconciled and handed over. The customer can choose ETL Tools performing the processing, ETL Tools building an automated solution, customer-operated workflows, or ongoing managed support.
- Understand the problem
- Review sample data
- Define transformation and validation rules
- Build the solution
- Test and reconcile
- Customer approval
- Deploy
- Document and hand over
- Optional ongoing support
Why ETL Tools
You get direct technical delivery from people who build ETL software
Advanced ETL Processor was created for practical data integration work, and that background shapes the service model. We care about visible rules, repeatable runs, rejected-row handling and outputs that can be explained without summoning the person who wrote the original script in 2014.
On-premise processing
Many solutions can run inside your own environment
Many ETL and database services can be delivered as self-hosted workflows. That lets the customer retain control of data, reduce unnecessary data movement, integrate with existing infrastructure and run processing in an environment they manage.
This is a deployment choice, not a blanket compliance claim. Security, access and data handling requirements should be agreed before data moves.
Customer-controlled options
- Customer retains control of data.
- Processing can stay close to existing systems.
- Workflows can be documented and handed over.
- Ongoing support is available when needed.
Featured service
Data Transformation Services are often the best starting point
Data Transformation Services is the broadest service offering. Start there when the data problem is complex, mixed-source or not yet clearly mapped to one specialist service.
NHS experience
NHS and healthcare work often needs careful validation and reconciliation
ETL Tools has experience with complex healthcare datasets, provider and commissioner-related processes, activity and financial data, data validation, reconciliation, Excel automation, large recurring datasets and business-rule-driven processing.
Questions
Frequently Asked Questions
What types of data projects can you help with?
We help with data services that involve moving, transforming, validating, integrating, converting or automating data. Typical work includes migrations, recurring ETL processes, Excel automation, data quality projects and legacy conversions.
Can you work with our existing database?
Yes. We can work with common relational databases, ODBC-compatible sources and older systems where suitable drivers or exports are available. Sample data and target requirements are usually enough for an initial review.
Can you work with legacy systems?
Yes. Legacy data work can include Access, FoxPro, DBF, fixed-width files, older SQL databases and text exports. The important part is preserving business meaning, not just copying columns into a newer box.
Can you automate recurring processes?
Yes. Recurring imports, exports, validation checks, file transfers, Excel processing and reports are strong candidates for automation. If the same task happens twice, it is already applying for a workflow.
Can the final solution run on-premise?
Yes. Many solutions can run inside the customer environment using self-hosted workflows. That keeps processing close to existing systems and avoids unnecessary data movement.
Can our team run the workflow afterwards?
Yes. We can build a customer-operated Advanced ETL Processor workflow with documentation and handover, or provide ongoing managed support if that fits better.
Can you handle large datasets?
Yes. Large datasets can be handled with appropriate workflow design, staging, logging, reconciliation and test runs. We normally start with sample data before processing full volumes.
Can you work with Excel-heavy processes?
Yes. Excel automation is a common part of ETL Tools projects, including workbook consolidation, template validation, database imports and report generation.
Do you provide NHS data transformation services?
Yes. We provide specialist NHS data transformation services for validation, reconciliation, Excel automation, migration, activity data and business-rule-driven processing. We do not claim NHS endorsement.
How do we start a project?
Send the source format, target format, sample data, approximate volume, required transformations, frequency, deadline and current problems. You do not need to know the exact service name before asking.
