Writing data to an open Excel file with XLNT

[ghost]

Hello,
Can you please tell me, can I, with the the library QtXlsxWriter, write some data to an already open excel file?

I tried to do it - as indicated in the example, but an error occurs, that is, the Excel cannot be written and saved in an open file.

Is it possible ?

If the file is open in another application it's generally locked for editing hence the error. This is an OS restriction, nothing to do with this library
