You use a linefeed as delimiter for "spreadsheet string to array", meaning you only get one colunm, each containing the entire line. When you convert to DBL, it only takes the numbers before the first character that cannot be part of a number.
- Change the delimiter to space.
- If you want to read it as strings, wire a string array to the type.
- You probably don't need to [open, measure, read, close]. Just read it.
