Enji.io
Enji.io is a cloud-first platform for structural engineering calculations that pairs a formula editor with reusable calculation libraries, Excel and REST connectors, and links into environments such as Revit and ETABS.
Enji Technologies presents Enji.io as a transparent, cloud-native place to author engineering formulas, keep symbols aligned with standards, and run large batches of checks without scattering opaque binary files (Enji.io marketing site, 2026).
The Microsoft AppSource listing for the Excel add-in explains that calculations run on a server while Excel or other clients call them through a REST API, which supports repeating spreadsheet workflows and bulk design passes (Microsoft AppSource listing for Enji.io, 2026).
Marketing pages highlight Eurocode-style examples, duplicate formula lines that show substituted values for review, and version history with audit trails for regulated work. Generative AI features are described for drafting calculation content into reusable components rather than one-off narrative reports.
Because pricing is not quoted on the short public overview alone, treat licensing as something to confirm with the vendor alongside any on-prem or private-cloud options mentioned in broader security copy.

Pros and cons
Pros
- Separates readable formulas from finished binary outputs
- Connects to Excel for familiar authoring while centralizing compute
- Speaks directly to construction engineering transparency goals
Cons
- Full enterprise pricing may require direct sales dialogue
- Teams must govern libraries carefully so shared components stay verified
- Deep BIM integration depth varies by connector maturity

Frequently asked questions
Does Enji.io replace ETABS or Revit analysis?
Enji.io focuses on transparent calculation libraries and connectors, not full finite-element building models. Use it alongside structural analysis suites for member checks and documented hand-calcs-style workflows.
Can Enji.io run inside Excel only?
Excel is one client. The platform emphasizes cloud execution with API access so other software can call the same approved functions without copying sheets manually.
Is Enji.io free?
The site promotes free templates and an installable Excel connector on AppSource. Confirm which tiers include private projects, SSO, and on-prem options with the vendor.
Which design codes does Enji.io support?
Illustrations reference Eurocode-style steel member checks. Ask Enji for the current catalog of built-in libraries and regions before you rely on it for a specific jurisdiction.
How does Enji.io handle generative AI?
Marketing text distinguishes between chat tools that output prose and Enji???s approach to structured, reusable calculation components. Review their latest AI policy for training and data retention rules.
Can calculations be reviewed like hand calculations?
The vendor stresses duplicate formula lines with substituted numbers to speed peer review, a common request in structural checking workflows.
