These are the row numbers that changed from 2024 in row parser:

16 -> 18
17 -> 19
18 -> 20
19 -> 21
20 -> 22
21 -> 23
22 -> 24
23 -> 25
25 -> 17
24 -> 16
36 -> 37
37 -> 38
38 -> 39
39 -> 40
40 -> 41
41 -> 36
124 - removed
125 -> 124
126 -> 125
127 -> 126
128 -> 127
129 -> 128
130 -> 129

Other than that, there's some person relationship mapping that got added cause we changed the input type in the template from string to integer and reduced options.

The easiest way to see the changes in the row parser from 2024 is in these 2 commits: Update row parser field numbers
Add "specified accommodation" to rent type mapping

And all the changes to csv parser should be contained here: Update csv parser

The rest of the changes are just connecting things together

Looks good to me! A few small comments. I checked the field numbers until my eyes glazed over, it's one of those things that's hard to check 100% though so testing is the way to go

Chcharces doesn't exist now, right? What's the difference now between this test and the one now on line 496?

[kosiakkatrina]

Yep, I think they might be the same! Removed it now

Nice, I'll fill this out
