Posted 23 August 2018, 10:15 pm ESTHi,
We have been having an issue when converting Excel files to SpreadJS. After importing the Excel file to our application, some of the formulas in the spreadsheet are lost, and a constant value is left in the corresponding cells where the formulas should be found. Also, the Excel spreadsheet has a number of named cells in it.
This issue seems to be recent, and we have no record of facing it over the past months. We are using the latest version of Chrome, SpreadJS 9.40.20161.0 and ExcelIO service.
