An easy work-around to designing a sim with Open Office spreadsheet is the following. Design your sim as normal, save as an .xls. Then upload the xls file to online EXCEL which will reformat to an .xlsx file. Re-save onto your computer being sure to maintain the xlsx extension and then upload to Epicenter. Even the range names saved using Calc are should be properly transferred from your calc xls to online Excel xlsx.
Friendly reminder that if your formulas don’t appear to work, Calc uses a semi-colon while Excel uses commas. Open Notepad, paste your formula into it, then find and replace these expressions and re-copy the formula back into your spreadsheet.
