Data bulk once a day from arduino

I would like send a data bulk once a day from Arduino UNO.How is the correct sintax when using the library "ThingSpeak.h", where to paste the timestamp of fields?Thanks for answer

Im sorry, the thingSpeak library does not include a function to use the buk data endpoint. Additionally, due to emmory constraints on the UNO, you may run into trouble saving up a lot of points.

Do you have access to a newer Arduino, or an ESP device such as the ESP32 or ESP8266?

There is an example in the documentation that will work. You may be able to get it working on the Uno if you have a wifi connection method.

It is solar power device in the nature, out of wifi, only mobile phone signal, bees, wolfs...  :-) .
I meant to do it like bulk the csv. It contains timestamp+values1.Specifically, I have 4 measurings a day, one measuring contains  two values.My idea is to send the string, where is timestamp1+value1+value2  +  timestamp2+value1+vaule2 + .............
% Is it possible?
