This guide explores how Excel Automation can rapidly generate electrical schematics in SOLIDWORKS Electrical using data-driven macros. It begins by creating macros with defined insertion points and variable fields, each formatted with percentage symbols so their values can be populated from Excel. The workflow continues with building a structured Excel file that lists macros, coordinates, file types and variable values, including manufacturer parts drawn from the existing library. Once completed, importing the spreadsheet automatically produces drawings with correct marks, descriptions and components. The video also shows how a user-friendly front sheet with drop‑downs can drive the main worksheet, enabling even non‑technical staff to configure modular systems quickly and accurately.
