Hi everyone,
I'm working on a flow to parse custom data from pdf invoices onto a spreadsheet. The flow is 90% complete but run into an issue. The steps of my flow are:
1. find folder containing PDFs
2. parse text from PDFs and store as variables
3. get first free row on Excel column
4. write variables to Excel column
5. Restart loops until all PDF is scanned
Here's what my flow looks like for each field.

Here's the problem. Some PDF has blank fields, so the column on Excel is also blank. But when a new PDF is scanned and it does contain value, then the blank field from the previous PDF gets filled in with the value of the new PDF. This is what it looks like.

Notice how the second row of column B is blank, then gets filled in by the third row? I want the new value to be pasted onto the third row and leaves the second row blank. Any idea how I should approach this problem? This is what I've came up with, but it is not working. Any input is greatly appreciated. Thank you for reading my long post!
