What is Peltier Tech?
Peltier Tech is a specialist Excel charting and data-visualization practice — part software vendor, part consultancy, part training provider — best known for add-ins that create chart types Excel doesn't build natively.
What it actually offers
- Charting add-ins. Excel add-ins that add custom chart types and formatting tools, so charts that would otherwise need manual workarounds can be produced directly. The company's own account traces this line back to a Waterfall Chart Utility in 2008.
- Consulting. Custom Excel work, including VBA- and template-based projects. The page describes work for small and large organizations in manufacturing, finance, government and the military, and cites a market-report builder that cut a monthly reporting task from two weeks to one day.
- Training. Sessions on formulas, charting, Tables and Pivot Tables, Power Query, VBA, dashboard reports and related topics, ranging from one- to two-hour seminars to multi-day courses, delivered at conferences, company sites or by video.
- A long-running blog. The site's blog and "cornerstone posts" are a substantial free reference for charting technique.
Who it suits
| If you are… | Peltier Tech is most useful for… |
|---|---|
| An analyst who needs Marimekko, waterfall or similar charts in Excel | Buying an add-in instead of hand-building the chart |
| A team with a recurring, awkward reporting process | Consulting to automate or restructure it |
| Someone who wants to get better at Excel charts generally | The blog and training sessions |
| A user who mainly charts in Power BI, R or Python | Less directly relevant; the focus is Excel |
Practical next step
Start with the blog to judge whether the author's charting approach matches how you work — it's free and shows the technique level better than any marketing page. If a specific chart type keeps costing you hours, look at the add-ins; if the problem is a whole process rather than one chart, consulting is the better fit. Testimonials on the page come from named users such as Lara K, Matt W and John H, one of whom reports learning an add-in in about ten minutes and using it to rework data ranges across roughly 110 charts — treat those as individual customer experiences rather than benchmarks, but they do point to the add-ins' main selling point: repetitive chart maintenance done quickly.
For broader Excel and visualization context, Chandoo.org and MrExcel cover general Excel skills, while Excel Campus focuses on everyday productivity.
What Excel chart types can Peltier Tech add-ins create that are difficult to build manually?
Peltier Tech's add-ins focus on chart types that Excel doesn't offer natively or that require awkward workarounds to fake. Based on the site's own description, these include:
- Waterfall charts — the original focus of the software line, dating to the 2008 Waterfall Chart Utility.
- Marimekko charts — variable-width stacked charts, cited by a customer as a favorite feature.
- Other custom chart types the site describes generally as "difficult and tedious to build in Excel."
Alongside chart types, the add-ins bundle formatting tools for manipulating existing charts quickly — the kind of repetitive work that otherwise means clicking through dialog boxes chart by chart.
Why these are hard to build manually
A waterfall chart requires invisible spacer series and stacked columns to get the floating bars to sit correctly, then custom formatting to distinguish increases from decreases. A Marimekko chart needs both column widths and segment heights to encode data, which means pre-computing a grid of values and stacking series in a specific order. Both are doable in plain Excel, but they break easily when data ranges change.
Who benefits
The clearest fit is someone producing the same chart types repeatedly — monthly reporting, dashboards, client deliverables. One customer quote on the site describes reformatting data ranges across roughly 110 charts and says the utility cut that from hours to minutes. That is the real trade-off: the add-in costs money and adds a dependency, but it removes per-chart manual setup.
If you only need one waterfall chart a year, building it by hand is reasonable. If you rebuild several a month, evaluate the add-in against your actual chart mix first.
Next step: list the chart types you produce most often, then check Peltier Tech's software page to see which of them are covered before committing. For background on the techniques behind these charts, the blog at Peltier Tech documents manual construction methods, which is useful if you want to judge how much time the add-in actually saves you.
How can Peltier Tech consulting reduce the time needed for recurring Excel reporting tasks?
Peltier Tech's consulting service is aimed at exactly the problem of recurring Excel reporting: work that must be redone monthly or quarterly, where manual chart and report assembly eats days. According to the site, past projects include a market report builder that cut a client's monthly reporting effort from two weeks to one day, and an add-in that applies company styles to tables and charts before exporting to PowerPoint. Those are the kinds of gains consulting typically targets—not one-off fixes, but repeatable processes.
Where the time savings usually come from
- Automating report assembly. VBA- and template-based projects build complex business models and report generators, so the monthly rebuild becomes a refresh-and-run step.
- Custom charts Excel doesn't offer. The charting add-ins cover chart types that are tedious to construct by hand, which matters if every report includes the same awkward chart.
- Standardized formatting. Applying consistent company styles to tables and charts before export removes the repetitive reformatting that quietly consumes hours.
- Operational dashboards. Commercial add-ins have been built to monitor and improve manufacturing processes, showing the same approach applied to ongoing monitoring rather than periodic reports.
Who this suits
Teams in finance, manufacturing, government and the military are named as past consulting clients, at both small and large organizations. The common thread is a recurring deliverable with stable structure—if your report changes shape every cycle, automation pays back more slowly.
A practical way to decide
Track one reporting cycle and note how much time goes to repetitive work (reformatting, re-pointing charts at new data, rebuilding the same layout) versus analytical work. If repetition dominates, consulting is likely to pay off. If analysis dominates, training in formulas, Pivot Tables, Power Query or dashboard design may be the better first step.
As a next step, look at the consulting page at Peltier Tech to see project examples, and compare them with your own recurring report. A useful criterion: if you can describe your report as a fixed sequence of steps repeated on a schedule, it is a strong candidate for automation.
What topics and formats are available in Peltier Tech's Excel training sessions?
Peltier Tech's training covers Excel topics tied to data analytics and visualization, and it is delivered in several session lengths and venues rather than a single fixed course format.
Topics listed
- Formulas
- Charting
- Tables and Pivot Tables
- Power Query
- VBA programming
- Dashboard reports
The site also says "and more," so the list above is not necessarily exhaustive.
Formats and venues
- One- to two-hour seminars
- Half-day and full-day classes
- Multiple-day courses
- Conferences, Meetups, association meetings, private company facilities, and video meetings
How to choose If you need a broad orientation, a one- to two-hour seminar fits. If you need hands-on practice with a specific tool such as Power Query or VBA, a half- or full-day class is the better match. For teams adopting a charting standard or building dashboards, a private multi-day course at your facility lets the material use your own data and workbook conventions.
A practical next step: check the training page for current topic outlines and scheduling, then match the session length to whether you want awareness or working proficiency. If your goal is mainly better charts rather than general Excel skills, note that Peltier Tech also offers charting add-ins and consulting, which may suit you better than a class.
Which Peltier Tech add-in should I use to automate formatting across many Excel charts?
For automating formatting across many charts, Peltier Tech's own description points to its Excel add-ins that extend Excel's charting capabilities, offering "formatting tools that make manipulating your charts quick and easy." That is the closest match to your goal: a formatting-oriented add-in rather than a single custom chart type.
The homepage evidence frames the add-ins around two jobs:
| Job | What the add-in is described as doing | Fits your need? |
|---|---|---|
| Custom chart types | Building charts that are "difficult and tedious to build in Excel" (for example, waterfall or Marimekko) | Only if you also need those chart types |
| Formatting tools | Making chart manipulation "quick and easy" | Yes, this is the automation part |
A practical reader scenario: you maintain a monthly workbook with dozens of charts that all need the same colors, fonts, gridlines and labels. You would install the add-in and apply a saved format or style across the chart set, instead of editing each chart by hand. One customer comment on the page, from John H, describes altering data ranges across about 110 charts after roughly ten minutes of learning the tool — that is the kind of repetitive, multi-chart task these utilities target. Treat that as a user's reported experience, not a measured benchmark.
Next step: open the Charting Software page from Peltier Tech and check whether your Excel version and platform (Windows versus Mac) are supported, then confirm the add-in includes a formatting or style tool rather than only custom chart types. If your charts are mostly standard types and your real problem is consistent styling, that formatting capability is the deciding factor. If you mainly need waterfall or Marimekko charts, pick the add-in that provides those instead.
For background on chart formatting decisions themselves, the Peltier Tech blog is the natural companion to the software. For general Excel charting questions, Microsoft documents Excel's built-in chart formatting options, which are worth checking before buying anything, since some repetitive formatting can be handled with chart templates or VBA.
What types of organizations and industries has Peltier Tech worked with on Excel projects?
Peltier Tech's consulting work has served both small and large organizations across manufacturing, finance, government, and the military, according to its homepage. That range suggests the practice is not confined to one sector: a small manufacturer needing a process-monitoring tool and a government or military team needing a complex business model would both fall within the described client base.
The page highlights project types rather than naming specific clients. Examples include:
- VBA- and template-based projects for complex business models
- Commercial add-ins used to monitor and improve manufacturing processes
- A market report builder that cut a customer's monthly reporting effort from two weeks to one day
- An Excel add-in that applies company styles to tables and charts before export to PowerPoint
These examples point to two broad audiences. The first is operations and manufacturing teams that need repeatable, automated monitoring or reporting. The second is finance, government, and military groups that need custom models, standardized formatting, or report-generation workflows. The market report example is the most concrete: it shows a recurring monthly reporting task where the value comes from reducing manual assembly time rather than from a one-off chart.
If you are deciding whether this kind of help fits your situation, ask whether your problem is recurring and rule-based — monthly reports, standardized chart formatting, or a model that must be rebuilt often. Those are the cases the described projects target. If your need is a single chart or a one-time analysis, the software and training pages may be a better starting point than consulting. The homepage lists separate paths for charting software, consulting, and training, so you can match the engagement type to the size of the problem.
