Studies show that 67.5% of plant engineers can't perform day-to-day jobs without Microsoft Excel.
In any field of engineering, whether it's civil, electrical, mechanical, instrumentation, chemical, process, and etc, Microsoft Excel has been the dominant engineering and reporting tool for decades.
For this reason, Open-Plant includes an 'Excel Addin' which is a basic feature of Open-Plant. The Open-Plant Excel addin supports Microsoft Excel 2007 and above.
