Steam's own export doesn't include your actual payout, only the net sales figure before Steam's cut. 70% is Steam's standard developer share up to $10M lifetime gross, so adjust it if your contract differs.

One per line: the exact product/game name from the report, an equals sign, then the game you want it grouped under. Steam reports each DLC and soundtrack as its own "game", so this has to be entered manually. It's saved in your browser session so you don't need to retype it next time.
