'Find/Change' fails for 'Change All'

Question

'Change All' fails where I use ' End of Paragraph' [^p] and 'Change Format'. Change/Find is fine but need to process a considerable amount of text.
e.g.
I am asking to change:
ABC £1,000 ^t £1000
to
ABC £1,000 ^p £1000
whilst changing format to new paragraph style, so it ends up like this:
ABC £1,000
£1000

Answer 1

OK. Thank you fo your patience
This is a real example.
I have this in a spreadsheet: 
I HJN
£29,995
8 DCN
£5,995
I ERK
£29,995
EBK I
£29,995
YEB I
£29,995
SOJ I
£27,995
I paste it into the InDesign text box and it looks like thus:
I HJN >> £29,995
8 DCN >> £5,995
I ERK >> £29,995
EBK I >> £29,995
YEB I >> £29,995
SOJ I >> £27,995
['>>' = invisible tab mark]
If I do 'find' ^t and change to ^p whilst specifying different paragraph style [which you would have to invent to replicate], I get:
I HJN
£29,995
8 DCN
£5,995
I ERK
£29,995
EBK I
£29,995
YEB I
£29,995
SOJ I
£27,995
But If I do it all in one go ['Change All'] Everything goes to the new style.
