Engineering Spreadsheet Solutions
Engineers are constantly using spreadsheets— whether they are performing design calculations, updating submittal logs, building cost estimates, tracking project budgets and timelines, running QA/QC checks, monitoring business metrics, or evaluating daily logs— Excel is our go-to tool as engineers. But when those spreadsheets turn into multi-tab monsters with broken links, formula errors, version chaos, and random math happening everywhere that only one person in the company understands, things can go really wrong, really fast.
Custom Excel Speadsheets
Smarter, Faster, Safer Spreadsheets for Engineering Firms.
At Custom Excel Spreadsheets, our founder and CEO is a Professional Engineer with 15 years of engineering experience. So we get it. That’s why we build the best engineer-grade spreadsheet systems to automate, validate, and streamline your engineering tasks and workflows — freeing your team to focus on delivering engineering value to your clients.
The Solution: Engineer-Grade Spreadsheet Systems
We take your existing Excel, Google Sheets, or Power BI workflows and transform them into professional-grade tools with automation, error-proofing, and documentation built in. We also build engineering solutions from scratch, fully customized to the way your team works and thinks.
Automated Data Workflows
Seamlessly import data from field logs, CAD exports, databases, or ArcGIS.
Integrated Dashboards
Interactive, visual reporting for management and clients through Power BI or dynamic Excel dashboards.
Validation & Error Checking
Built-in checks that flag input errors, unit mismatches, and inconsistent data before they cause rework.
Audit & Documentation Controls
Version tracking, input logs, reviewer initials, and change history.
One Click Reporting
Generate clean PDFs or submittal-ready packages automatically from your workbook.
Powerful, Intuitive Engineering Calculations
Run professional design calcs quickly using a spreadsheet that is easy to understand and use so that you don’t spend hours training and retraining new users.
Scaling Pains
Some clients start out with a system that works fine for a small team of 2 or 3 salespeople. Then, as their business grows to 5, 10, or 20 salespeople, that old system can’t keep up, leading to late nights, late payouts and ultimately a hinderance to their team’s growth and performance.
Custom Excel Speadsheets
Our systems eliminate redundant work and make your spreadsheets reliable enough to stand up to client review, QA/QC, or internal audits.
Our Partners in Industry
Industry We Serve
Our engineering spreadsheet systems are tailored for a range of engineering disciplines — each with unique data and calculation needs.
Civil & Structural Engineering
Stormwater modeling, grading, pipe networks, load calcs, quantity takeoffs, and more — all streamlined through automation and quality controls.
Mechanical Engineering
Heat load calcs, pump & fan sizing, pressure loss analysis, or maintenance tracking — optimized for speed, accuracy, and repeatability.
Industrial Engineering
Production tracking, equipment performance logs, inspection data analysis, and process reporting — turned into robust, automated systems that scale with your operations
Our Approach
We use a structured, engineering-minded process to ensure every system we build performs reliably and consistently.
1. Discovery & Triage
We review your current spreadsheets to identify inefficiencies, risks, and automation opportunities.
2. System Design
We re-engineer the structure, build automations, and implement clear inputs, checks, and outputs
3. Validation & Testing
Every spreadsheet is reviewed and tested for reliability, accuracy, and clarity.
4. Documentation & Handoff
We provide clear instructions, version control, and user documentation so your team can maintain confidence over time. We can also provide user-training videos with any solution we build.

Custom Excel Spreadsheets
When “Good at Excel” isn’t good enough.
As an engineer or engineering Firm, do you really need to hire an Excel professional? Most engineers consider themselves to be proficient at Excel. They’ve been building spreadsheets since undergrad (if not before) and so they know their way around the tool pretty well. For many Excel projects and tasks, an engineer on your team who is good at Excel is good enough.
However, there’s also a dangerous side to this engineer-excel love affair. What we’ve learned over more than a decade of both engineering consulting and spreadsheet development is that engineers’ love for spreadsheets can be quite costly.
We’ve found that there are a few main culprits that lead to significant losses for engineering teams with respect to their spreadsheet usage:
Lost Time
Lost Time – Even small engineering teams spend hundreds of hours a year building, revising and debugging spreadsheets. Instead, those hundreds of hours could have been spent meeting project deadlines, completing billable engineering tasks and delivering excellent solutions to their clients.
Costly Errors
Costly Errors – When critical spreadsheets are developed in-house, the potential for error increases significantly, especially as they are used and modified over time. Spreadsheets that lack proper design, QA/QC, and protections can easily output erroneous results leading to errors in project design, billing or scheduling (to name a few).
Spreadsheet Guy Syndrome
Inevitably on engineering teams, one person will become the go-to guy for all things spreadsheet related. Viola, you’ve got your own in-house spreadsheet expert! Well, not exactly. What you really have is an engineer who faces constant distractions from their billable project work because they are constantly bombarded by spreadsheet requests.
Inefficiency
Engineers are great at figuring things out and solving problems on the fly, and that’s how many engineering spreadsheets are built. The result is something that works. But not necessarily something that works as well as it should. Problems with U/I design make it clunky and require extensive training for new hires. Missed opportunities for automation require manual work. Improper formula choices or poorly written code leads to error messages and debugging.
At the end of the day, engineers are professional engineers—not professional spreadsheet design and development experts. You have a knack for spotting where a good spreadsheet could be used. We have a knack for building that spreadsheet to do exactly what you need— faster, at a lower cost and with more advanced and reliable capabilities.
