The patch created by Potato_of_Doom is not available anymore and I found
a way to transfer saves from Switch to PC without cloud saves!

Here is the English translation:

The main issue is that the latest version for PC (1.32) is "older" than the latest version for Switch (1.60). Because of this, you can bring saves from PC to Switch (they will be automatically converted by the game), but you can't do it another way around.
However, there is a workaround. You can use
Offzip.exe software to unpack the save file and
some HEX editor to change the version of the game inside the save the file.
1. Make a backup of the game saves using
Checkpoint and copy the desired .png and .sav files to your PC.
2. Download the
Offzip ( ht tps ://aluigi.altervista.org/mytoolz.htm#offzip ) software and unpack it somewhere. For simplicity let's say you unpacked it to the folder "new" at the root directory of D drive (
D:\new )
.
Open the command line and enter the following command:
path_to_file_Offzip.exe -a path_to_save_file_from_switch path_to_folder_where_to_save_file_for_pc 0
Example:
D:\new\offzip -a D:\new\ManualSave_5a81a_7e40f000_5e09c00.sav D:\new\pc_save_file 0
The extracted file will have a similar name: 0000000c.snf.
3. Download and install som HEX editor (the author of the solution uses
HxD ( ht tps ://mh-nexus.de/en/hxd/ )). Open the .snf file (from the "pc_save_file" folder) in any convenient HEX editor, and go (the key shortcut for HxD is Ctrl + G) at offset
C16 and change the value to
12 (your value can be 15 or 14 or something else, it doesn't matter - change to 12). Save changes and close HEX editor.
4. Rename recently edited .snf file to the name of the original save file from the Nintendo Switch (e.g. ManualSave_5a81a_7e40f000_5e09c00.snf ) and copy it along with the .png file with the same name to the directory with saves for your Witcher 3:
...My Documents\Witcher 3\ gamesaves
5. ...
6. PROFIT
You should be able to load modified save at your PC.
PS Works only with manual saves. This method doesn't work for autosaves.
The author tested this with 1.31 GOG, I tested with 1.32 GOG, some folks in the thread confirmed that this method worked with the Steam version as well.
