Hi. Whether spire.xls can be used to read and write data to current spreadsheets already open?. Because I just saw it working offline. Sorry I'm new and I'm waiting to be able to work with both features. Thanks you!
Thanks for your inquiry and sorry to reply late for weekend. It is impossible to read or write Excel file using Spire.Xls when the file is occupied by other processes. There will be an exception. You need to close the file first, then operate it with Spire. Any question, welcome to contact us.
