EXCEL CONSULTANT

  • I have worked on over 1,500 Excel expert consultancy projects both large and small for over 550 clients for over two decades.
  • Not only do I specialise in using Excel but I have also personally managed significant national and international IT and non-IT projects and made business improvement assessments and recommendations. I can therefore also provide a second opinion on how to make use of the results in your business and make suggestions on improvements from a business perspective.
  • It is my understanding of what the results are used for and their additional interpretations that will make my expert Excel work more meaningful and useful to you. I am a power user of Excel from managing real-life projects myself which allows me to act as an Excel consultant not just as an Excel trainer.

Colin Middlemiss, Communications and Engagement Manager, Yorkshire Water

“Peter assisted us with automation of a manual Excel process, although each individual instance only saves a couple of minutes, because we run the process many times per day the aggregate time savings are huge. This has freed up my team to spend more time on added value tasks and has also reduced the instance of human error in process. This is a huge benefit to our reporting, and we will definitely we reviewing other processes with a view to further automation.”

Matt Davey, Group Financial Controller, Flakt Group

“We initially approached Peter from discovering his unique skill set via Google as the Excel Expert as we were considering the development and implementation of a new costing process. We were in the process of reviewing a semi-automated commercial costing template to enable a quicker more accurate pricing. Peter has now made our quoting process 40% quicker and with greater accuracy too.
Peter immediately understood all the relevant critical costings needed to develop such a document. We have Excel competent people within the business but far far from Peter’s level, his knowledge and passion is exceptional in this particular subject. Peter has implemented functionality we never thought was possible. We would wholeheartedly recommend Peter for all aspects of Excel from comprehensive data challenges and commercial costing proposals to general advice and automation within Excel. Also, a very pleasant person to do business with. We will be in touch again.”

Tim Hughes, Managing Director, CHH Conex Limited

“Peter helped us overcome an Excel challenge turning software codes into an Excel task scheduler using calendar dates and times, which we initially thought was impossible. He also did it in super-fast time, in a way so easy, that anyone could operate it regardless of their Excel knowledge. It’s literally a 3 click process. The overall saving to the business (Software and administration hours) exceeds £10K p/a, however the fact that anyone can now operate this model is simply priceless.”

Peter’s experience and knowledge are powerful tools which we would recommend you harness the power of for your own business.”

Gemma Price, Superfood Market

“As a small business owner my time is in great demand; Peter’s work has enabled me to carry out some of my routine tasks in a fraction of the time it usually takes, enabling me to me to spend my time on more important matters. He has also created a piece of work that far exceeded my expectations, using his Excel experience to improve on my ideas. I’m delighted with his work and would heartily recommend him to others.”

Charlotte Baldwin, Colour Your Garden

“I had a client with a jumbled up selection of spreadsheets containing almost 40,000 shoes and after spending the best part of a week editing the data so that it could be imported into a online store I decided a professional was needed. Peter’s website stood out from the rest and gave me a good feeling. A quick email describing what I needed and a few back and forth additional emails resulted in my data being ready in just a few hours. I’d estimate that Peter has saved me 6 weeks or more of boring work. I’ll be using Peter’s service again for sure and would encourage anyone with a lot of products to import to give Peter a go as the cost was very reasonable.”

Richard Jordan, Handcoded.co.uk

“I knew we could be doing more with our data, but wasn’t sure what was possible, and didn’t have time to investigate. I have a good knowledge of Excel, but using Peter was absolutely money well spent. It wasn’t just that he was able to do things much quicker and more elegantly than I could, it was that he was very quick to grasp the issues, ask the right questions, so that the whole process was easy and quick. We’re able to use our data much better now as a result.”

Michael Mann, Head of Operations, Mathematics Mastery

“Peter easily achieved all the agreed outcomes with all stages fully completed and often exceeded; Peter consistently took initiative to promote the project and strengthen business aims and relationships.

Peter provided a seamless link to our sub-contractors in the UK and proved personally essential in framing internal expectations, providing additional value to elements of the proposal formerly covered by others, without friction. Peter was a very popular and valuable member of our team.

Peter’s analytical knowledge and application of skills using such tools as MS Excel and other computer programs was extremely helpful. His efforts, often in excess of expectations, to assist the whole team were immeasurable.

Peter sees problems very clearly and can quickly grasp complex issues, thinking swiftly through options and providing clear solutions.

.

All of Peter’s work is very well presented, clearly organised and critically evaluated at each stage, his use of written language is excellent and his ability to depict his solutions in graphic format are equally admirable. In short he is a joy to work with and I would highly recommend his services to others.”

Tim Washington, Managing Director, Walk Consulting Group

“I run a small charity which is undertaking a household survey in rural Kenya. I spent just under 90 minutes working with Peter and I know that his input has saved us at least 3 weeks of work in collecting and analysing our data. I’m fairly new to using Excel, but Peter pitched his advice at a level that I understood and left me feeling confident that I can implement the strategy he recommended”

Ben Skelton, DigDeep (Africa)

“Morgan’s Historic & Classic Vehicle Events Yearbook is a directory containing more than 1000 events with a mailing list of 4000+ subscribers raising £250,000 for charity in just 11 years. The efficiency of the production, distribution and accounting processes is highly-dependent on a suite of Excel spreadsheets that have been developed and enhanced in close co-operation with Peter. We can now offer the best possible service to our subscribers, maximise the benefit to charitable causes and make the most productive use of our volunteers’ time. Peter’s ready understanding of our requirements, the inventiveness of his solutions and speed of response must surely be without equal.”

Tony Raylor, Editor – Morgan’s Yearbook, York Vikings Rotary Club

“Peter has been extremely helpful towards finding a solution for our reporting requirements. Even when the macro needed to be amended on numerous occasions, he was open to our suggestions and promptly implemented new fixes without delay.”

Jane Tully, Head of Insight and Engagement, Money Advice Trust

“Thanks again for your excellent work. It seems to work well, so much so that I’m alarmed to realise just how much time I’ve been wasting doing this myself!”

James Benford

“While creating a works request briefs to send to potential contractors we have to pull information from several different resources, this is both time consuming and repetitive.
I approached Infinite Innovations Ltd to see if it was possible to hold all this information in one document and select different information as necessary, during our initial consultation Peter quickly identified areas he would be able to automate and suggested other ideas I didn’t even know were possible to do in Excel like creating PDF documents from different sheets within the file and pre writing emails to send to our contractors.
Peter kept in close contact through the creation process with regular updates and test versions for me to try and modified the file as we found other improvements to speed up the data entering.
It has been a pleasure to work with Peter on this project, his knowledge of Excel is second to none, if he hasn’t got the solution to your problem no one has!”

Peter Sherwood, Maintenance Manager, Canal & River Trust
