This component wraps an existing Microsoft Excel file which is linked to RCE. The general principle is:
Copy of the existing Excel file as temporary file in a temporary folder (working copy)
Wait for all input channels which are needed to run the component (depending on how input handling and constraints are set)
Execute VBA-macro “Before Excel run”
Copy all input channels to their specific cell ranges. If there are multiple values in an input channel the first value occurring will be copied (“first in, first out”).
Update all formulas
Execute VBA-macro “After input variables are written”
Update all formulas
Read all output channel values from their specific cell range
Execute VBA-macro “After Excel run”
Delete temporary Excel file
