In Mike's example, you cna change the constant 2 to a control which allows ytou to select which line to write to.

2 meaning the third position becasue indexing starts at 0.  😉

I read the question as wanting to insert text into an already existing text file. If that's the case, you need to read in the text file, insert your text, and then write out the new text to the file.

Could be wrong though.

@Mike can you tell me what is the name of that block which is  deciding line number (input "2")

It is 'Replace Array Subset' (https://zone.ni.com/reference/en-XX/help/371361R-01/glang/replace_array_subset/ )
