I have created xls file using this library,
https://github.com/andreac/RSSheet/tree/a3a1c3f9802e67508a773399007ffb9ebf8135c6
But I only can open the created xls file on PC or MAC and I cannot open it on IPAD using any software.
My client want to open it on IPAD, I tried .CSV, and it can be open on any device.
But I cannot create Multiple sheet in .CSV.
I spent too much time on this.
Does anyone have any suggestion?
Thank you.
