NExS lets you load and save spreadsheet files stored in the popular WKS and WK1 formats using the Open... and Save... operations. When importing WKS/WK1 files, NExS clears the current spreadsheet, if there is one, and loads the entire WKS/WK1 spreadsheet along with its default characteristics such as column width and format.
Note that there are differences between spreadsheet programs, so you may have to modify certain formulas or cells to get the spreadsheet to work properly in NExS. You can load most spreadsheets without any difficulty, but those with complex interactions that use macros or certain functions will require some modification. In addition, with the Import... operation, you can load tabular data from text files in several formats which include comma-separated values (CSV) and tab-separated values (TSV).
