Posted 5 May 2022, 4:54 am ESTAs the title says, I am importing ExcelIO in my React Application just as in the tutorial
"import ExcelIO from '@grapecity/spread-excelio';"
ExcelIO.LicenseKey = SpreadJSKey;
But this is the error that I get , see image attached
I have also tried importing as
"import * as ExcelIO from '@grapecity/spread-excelio';", but this time it would say that it is read-only.
What am I doing wrong?
