Opening a CSV text file
CSV (comma-separated values) text files contain data in the form of pairs of X
and Y values (the values can be evenly or unevenly spaced). If you save a
spectrum as a CSV file, you can process the data using a spreadsheet program or
other program that uses the CSV file format. You can then use OMNIC to open
and display the file as a spectrum and save it if desired as a spectral data file (with
the extension .SPA) with the axis units you specify.
The CSV file must meet the following requirements to be opened:
• It is a text file (with the extension .CSV) consisting of a list of pairs of X and
Y values.
• Each pair is on a separate line and each line is ended by pressing the Return or
Enter key.
• There is a comma, tab, space or line feed between the X and Y values.
