Sorting and filtering text

[Bambambigelow]

Hi,

I have to prepare evidence for a court hearing and need to filter through 3 years of whatsapp messages.

I can export these into txt. and word. Documents.

Is there then a way to filter out my replies?

Eg,
Export
1/1/2020 16:30 - x: hi
1/1/2020 16:31 - y: hello
1/1/2020 16:32 - x: how are you
1/1/2020 16:33 - y: I'm ok
1/1/2020 16:34 - y: how are you
1/1/2020 16:35 - x: great thanks

Result
1/1/2020 16:30 - x: hi
1/1/2020 16:32 - x: how are you
1/1/2020 16:32 - x: great thanks
