Export CSV file

I need help to read 2 real type signals from an esp32, write records every 30 minutes in a table. One column must have date and time, another with the data, for example 30.97.
Can I do an automation so that every day at 24h a table with the data of the day is exported?
Where can I export this data to? Just for an email?
What is the cheapest plan to do this?
Any tutorial to help me?


Perhaps this documentation will be useful to you https://docs.blynk.io/en/blynk.console/devices/actions-with-devices#bulk-actions

You can also use Node-RED to send data to a Google Sheet every time the device receives an update of the Virtual Pin value from the server or app. Something like this
