I searched for importing data into database from excel using DHTMLX. But I saw only links related to excel exporting. Is there excel importing functionality for DHTMLX?
There is no official solution for such use-case
You can try one of next workarounds
a) convert excel to csv, most components can load data from csv format
b) php connector can be used to load from excel files, it is not officially supported anymore - but still must be possible hopevalleyrv.ca/extension/dh … _file.html
