Add Formula To Cell
Add Formula To Cell Action is a spreadsheet action that enables the user to insert a formula into a specific cell of an open Excel (.xlsx) variable file. The formula is written to the cell but not evaluated or applied at the time of insertion.
A typical use case, is dynamically populating formula logic during an automation run.
Appearance
In Talos, Add Formula To Cell appears as a standard rectangular node with a file-import icon, indicating an operation that writes content into an existing Excel file.

This must refer to a variable that holds an already-opened Excel document. The variable is typically populated by a preceding Open Spreadsheet action.
Ensure the file is open before this action executes. Referencing a closed or uninitialized variable will result in a runtime error.

Examples

When targeting multiple cells, the same formula will be inserted into each specified cell.
Provide a valid Excel formula string. The formula should begin with = as it would appear in Excel.
The formula is inserted but not applied. It will not be evaluated until the file is opened or recalculated in a spreadsheet application.
Examples

=IF(B2>100, "High", "Low")
=CONCATENATE(C1, " ", D1)
