ESP32: Save data into xls in sdcard

Projects Programming
1

Hi,

My project needs to write to an xls in sdcard using Esp32 Devkit/Arduino platform. How do I do it?
I know how to connect sdcard to ESP32 and use FAT32, however I dont know how to create/open xls on sdcard and write to it.

Thanks and Regards,
WonderfulIOT

Why not write to a .csv file instead of an .xls ?

Writing a CSV file is straightforward.

If you find a way of creating an XLS file with an Arduino, do let us know.
