To use them in the expression, enclose the variable name in percent signs ( %). Variables created in ModelBuilder can be used by this tool, but variables desired for use in the expression parameter cannot be connected to the Calculate Value tool. For example, if you use the Calculate Value tool to calculate a distance for use as input to the Buffer Distance parameter of the Buffer tool, specify Linear Unit for the Data Type parameter. The Data Type parameter is used in ModelBuilder to help chain the output of the Calculate Value tool with other tools. This tool is intended for use in ModelBuilder and not in Python scripting. The inner model runs all of its processes once per feature class, and then the Calculate Value tool runs once at the end to output the CSV file once and only once.Returns a value based on a specified Python expression. I have tested this with ModelBuilder and got it working (see screenshots). I do not think this actually has any effect, it just makes it more clear visually as to what's going on. (Optional) Connect the input variables and inner model outputs to the Calculate Value tool as preconditions.The sole output of the outer model is the CSV file. (Optional) Expose the input and output variables as model parameters if you want to be able to run them from the model's tool dialog or chain it together with other models/scripts.

Add a variable of type Folder to allow you to specify where to create the output CSV file.Create a new model - this will be our "outer" model.Outer Model - Runs inner model, runs Calculate Value tool just once when inner model completes:

Do this for each of the outputs of the Collect Value tools as well as whatever input parameters you need such as the Input Workspace. Expose the input and output variables as model parameters (right-click an oval and check Model Parameter).

You can do this using the Calculate Value (Data Management) tool and some Python magic.
