1.  As I recall, you are using LabVIEW 7.0.  In this version, you have to wire a numeric array to the Write To Spreadsheet File.vi.  Otherwise, you will get an error and a broken wire, as shown in the attached image.

2.  You are probably referring to the content of the file.  The difference on the block diagram is shown in the 2nd image below.  The Write To Speadsheet File converts the numeric data to string and Tab delimits the data.  If you do this conversion, and delimit the data (tab, space, etc), then you essentially do something similar and can simply use the write character to file.  In the next post, I'll show the insides of the Write to Spreadsheet VI..  Hopefully you'll see the resemblance.  Hopefully, it won't confuse you, and code those days were rather messy 😞

3.  To edit your message, click on the Options at the right top corner of your post and select Edit Message.  You only have (5??) minutes to do so (from the time of the original post).

See attached images..  Hopefully they won't confuse you 😉  I cleaned up the image for clarity of reading only..  The "messy one (at top) is the original VI from the Functions Palette.

what I mention is the difference of the output between speadsheet and characters to file?
izit the same?

[elo85]

this is my block diagram, hopefully everything run smoothly without any problem.
tomorrow I'll try to plug to the source measure unit to see whether can get the graph in jpeg file and the save the data.

If you delimit the data using Tab (\t) for characters to file, then they will essentially be the same.  We're talking about the contents of the datafile, right?  In other words, if you open the data file using (let's say) Notepad, or better Wordpad, then they will look the same.

Actually, a fun exercise is to try both.  Look at the output file and compare.  It's a good learning exercise.  You can then play with different delimiters, etc..  and play with the formatting.. (something to do on a rainy Sunday afternoon 😄 )

Another good exercise is to follow the directions at the bottom of the diagram for Write to Spreadsheet File to make a copy that can have a string array as an input.
