A Testimonial to the Quality of our Services
Lumen jumped on a call with me and not only listened to exactly what I required but made suggestions on how the sheet could be improved even further.
The finished product was received a couple of days later, and it functioned exactly as I had intended it to. Overall, I was very impressed with the service, quality of the work and suggestions provided.

Thank you both for “dropping everything” to help me solve my problem, Josh, you did it, and blazingly fast too.
Words are insufficient to voice our deep appreciation. We are amazed to receive such professional quality help, so fast and with such a deep sense of empathy and understanding.
Gentlemen, I used to teach four types of exchange:
1. No exchange (rip-off)
2. Poor Exchange (some value but not to the expected standards)
3. Fair Exchange (expected level of service and quality) 4. Exchange in Abundance (Better than expected quality, service, care, etc.)
Most businesses operate on the 3rd type of exchange, however only the 4th type guarantees growth and long term survival. Well done on your superlative service.
The label macro is working perfectly and we’ve almost caught up the backlog.
Many Thanks,
Terry Le Sueur - Director

Excel Programming FAQs
What is Excel programming and why does my business need it?
Excel programming uses Visual Basic for Applications (VBA) to automate tasks, build custom tools, and extend what Excel can do far beyond standard formulas. If your team is spending hours on repetitive data tasks, running reports manually, or copying and pasting between sheets — Excel programming can eliminate all of that and free your people up for higher-value work.
What kinds of tasks can Excel VBA automate?
Almost anything repetitive can be automated. Common examples include generating and formatting reports at the click of a button, automating data imports and exports, sending emails from Excel, updating dashboards, running calculations across large datasets, and populating templates with live data. If your team does it more than once, we can likely automate it.
What's the difference between an Excel programmer and an Excel consultant?
An Excel consultant focuses on strategy — understanding your business needs and designing the right solution. An Excel programmer builds it, writing the VBA code, Power Query transformations, and formulas that make everything work. At Lumen, our team does both, so you get a solution that’s technically sound and actually suited to how your business operates.
Can you fix or improve an Excel file someone else built?
Yes, and it’s one of the most common things we do. Whether a macro has stopped working, a spreadsheet is running slowly, formulas are producing errors, or you’ve inherited a workbook no one fully understands — we can diagnose the problem, clean it up, and get it working reliably again. We can also add new functionality on top of existing files where needed.
Do my staff need to know VBA to use a solution you build?
Not at all. We build solutions that anyone can use — typically with simple buttons or forms that trigger the automation behind the scenes. Your team doesn’t need any programming knowledge to run a macro or refresh a report. We also provide training and documentation as part of every handover so your staff feel confident using what we build.
Can Excel integrate with our other business systems?
Yes. Excel can connect to SQL databases, REST APIs, CRMs, accounting platforms, and other data sources using Power Query and VBA. This means your spreadsheets can pull in live data automatically, removing the need for manual exports and copy-pasting between systems. We also help businesses extend their Excel reporting into Power BI for more advanced interactive dashboards.
How long does an Excel programming project take?
It depends on the complexity of what you need. Smaller fixes and automations can often be completed within a day or two. More complex custom applications or integrations may take one to three weeks. For urgent work, we offer same-day or next-day assessments and can prioritise accordingly. We’ll always give you a clear timeline before we start.
What Excel programming services does Lumen offer in New Zealand?

We work with businesses of all sizes across New Zealand, from SMBs to enterprise clients.
How much does Excel programming cost?
Pricing depends on the scope and complexity of your project. We offer three flexible models: an hourly rate for quick fixes and minor work, fixed-price projects for well-defined deliverables, and ongoing consultancy for businesses that need continuous support. The best starting point is a free consultation — we’ll assess your needs and provide a clear, no-obligation quote.
