Unit Modding
 Two files are used:
Local Disk > Program Files(x86) > Slitherine > PanzerCorps2 > PanzerCorps2 >  Content > Editor > Data > equipment.pzeqp
Local Disk > Program Files(x86) > Slitherine > PanzerCorps2 > PanzerCorps2 >  Content > Data > Units.csv

The game uses Unit.csv, the Devs use equipment.pzeqp.

equipment.pzeqp is a TSV file, tab separated data. This is a modification of the same file used in PzC.
It allow comments to allow you the keep track of revisions.

In the editor: Edit > Unit Tools , this opens the ‘Unit Tools’ window. 
Pushing the ‘Export to Game’ creates a new Unit.csv file.

-----------
To edit equip file
1) make a safety version.
2) Add .csv to file name - equipment.pzeqp.csv
3) Open equipment.pzeqp.csv in spreadsheet. I use LibreOffice.
 Charactoer set: Unicode (UTF-16) , or just Unicode, NOT UTF-7 or UTF-8
 Separator Options: Tab
4) Save in spreadsheet format of your choice. [.xls, .ods]
5) Tweak page for easy reading.

Mod away.

-----
To transfer to game.
File > Save as > Text CSV; Click on Edit filter setting
  Charactoer set: Unicode (UTF-16) , or just Unicode, NOT UTF-7 or UTF-8
 Field Delimiter: Tab
 String Delimiter: null

Move to Editor > Data ;

Use editor to export to your game directory.

Note: I do all my equip file editing on my Mac Air.
You should come up with a method keeping track of your mods vs the original game set up.
