The "Array to spreadsheet string" function apparently puts in a "carriage return, new line" pair every four lines (one "row" of the original array). I could find any setting that prevents it, not sure why it shows up as a space, but if you put a "search and replace" (from the string function pallette) and search for a "Carriage Return Constant" and replace with an "Empty String", setting the optional boolean "Replace All?" to true it removes them.

Very good, thanks. The headshot faster from forum.

What is actually happening is that you are getting a \r\n at the end of each "row" of the 2D array. You are not getting a space. This is well-known behavior of the Array to Spreadsheet String, and is also documented:

Converts an array of any dimension to a table in string form, containing tabs separating column elements, a platform-dependent EOL character separating rows, and, for arrays of three or more dimensions, headers separating pages.

On Windows the EOL character is \r\n. So, each row will have a \r\n. If you were to use a tab instead of a \r and set the indicator to "\" display mode you would see this behavior:

Others have already explaine what is happening. Here's a better way to do all this. Modify as needed.

(It seems useless to first built a 2D string array just to convert it to a spreadsheet string later. This can be done in one step. :))
