Importing and Exporting CSV Files

You can save or load data to comma-separated value (.csv) files. You can also specify whether to load unformatted text or headers when loading a comma-separated file.

Use the getCsv file method to save the data to a comma-separated file and the setCsv file method to load the data. Use the TextFileOpenFlags type to specify the import options.

Using Code

The following code saves and loads a CSV file. Select button 1 to save and button 2 to load the file. Change sheets to see the results.
