Why direct import is not available

Structural Toolkit uses a proprietary spreadsheet format that does not export to anything Calcs.com can import. The practical path is to rebuild your standard templates in Calcs.com. Most engineers report this takes a day or two for their core set of calculations, and the result is a linked workflow rather than a folder of separate sheets.

​
Start with your standard templates

Do not try to move everything at once. List the calculations your office actually repeats. That is usually a short set: a few beam types, a column, a footing, and a connection or two. Rebuild those first in Calcs.com. Most engineers report that rebuilding a core set takes a day or two.

​
Rebuild as linked calculations, not separate sheets

The rebuild is a chance to improve the structure rather than copy it. Calcs.com connects calculations through live load paths, so a beam reaction can feed the column that supports it. See Linking Loads and Reactions Between Calculators. Engineers who rebuild this way end up with a connected project rather than a folder of independent sheets. Change a load at the top and the members below it update.

​
Check coverage before you commit

Run two or three recent jobs through Calcs.com and compare the results against your Structural Toolkit output. It confirms that your standard member types, materials, and regional standards are covered. It also builds confidence in the numbers before you rely on them. A free trial is the usual way to do this.

​
Keep Structural Toolkit running during the changeover

There is no need to switch off Structural Toolkit on day one. Most teams run both for a period, then retire the old calculations once the rebuilt versions have been used on real jobs. See Migrating from Spreadsheets for how to run both side by side. If a calculation you rely on does not appear to have an equivalent, email support@calcs.com before assuming it is missing.

Calcs.com covers AS 1170 (loading), AS 1720 (timber), AS 3600 (concrete), AS 4100 (steel), and the core Australian standards Structural Toolkit addresses. It also covers NZS, IBC, ASCE 7, AISC 360, NDS, and Eurocode 2 and 3 in the same platform. See Standards Available. If you rely on a specific calculator, contact us before switching and we can confirm coverage.
No. Calcs.com is a cloud platform and requires an internet connection. The benefit is that your calculations are accessible from any device, and your team can collaborate in real time without managing local installs, and there is no Windows-only install or license-monitor utility to manage. See System Requirements.
Yes. ClearCalcs became Calcs.com in 2025. It is the same product, built by the same team, under a new name. See ClearCalcs Is Now Calcs.com.
