Hi,

I hope "Read Lines from File.vi" found in FILE I/O Pallate will help you to read the file interms of lines. It also gives the EOF info also i think. Then you can process the strings whatever way you want. All the VIs to process the strings available in strings Pallate.

all the best.
Thanks,
Logic

Quick answer : if your file is not too large, load it in memory as a 1D array of strings, then use the "Decimate array" function, convert back the string array into a spreadsheet string and save.
