This is the chat file exported from an instgram .json file
This is how I want to alter the date format to look like
I am trying to edit the exported chat file in .txt format and change the format of dates to look like the second picture so that file can be used is usable in chat analysis tools. The timestamp is not required to be precise right down to the second and I would rather have that upto minutes only.
I couldnt find a suitable script to make this change and I'm running ubuntu.
