Finally, an afforable alternative to spreadsheets

The Affordable Alternative toSpreadsheet Wiring Design Software

Stop fighting with Excel formulas and manual calculations. EZ Wire eliminates spreadsheet chaos with purpose-built harness design software.

Why Spreadsheets Fail for Harness Design

Spreadsheets weren't built for wiring harness design. Here's what goes wrong:

One broken formula can cascade through your entire spreadsheet

Hours spent on manual data entry and formatting

Duplicate pins and invalid connections go unnoticed

Connector pinouts must be re-entered from scratch for every harness

Connector definitions live in separate files with no shared, searchable library

Wire specs are stored as free text - nothing stops incorrect gauge or color data

See why professionals and hobbyists alike are switching from spreadsheets to EZ Wire
