Want to use php Office / php Spreadsheet to create a NEW sheet (xlsx file), populate rows & columns, I'll build the loops, etc.
Very frustrated, cannot find a single example of all the steps needed to do this; create a new instance, populate cells, write to an xlsx file.
It's real big on how to read, ZERO examples I can find on how to write.
Please someone show me. a FULL example, one if I run it, it will literally produce an xlsx file.
Using this, tried every way of asking I can think of, ZERO results.
