See for yourself by reading reviews on the most popular resources:
I found it relatively easy to use, it would be nice if it had an undo selection. And getting the right size font was not easy. Had to wait for print out to see.

It works, almost a must have thing. But not everything is perfect, there are some limited options. But you will never get it perfect because it is not an original document.

Ease of use. I was able to tab over to next box throughout the form. There was no need for the prompt, and I. was unable to disable it. Otherwise, it was quick and easy.

A good way to reduce your Excel file size is to get rid of the empty rows and columns. Here's how to do that: Select all unused rows and columns (Shortcut = Ctrl+Shift+Right/Down Arrow) Right-click > Delete.
This is what makes the file so large: Excel is picking up a lot of empty cells and thinks there's data in them, which then it tries to save into the XLSX file on disk, and because it needs to keep references to all those hundreds or thousands of cells, the file size gets overblown.
