# About CSV export

Use the CSV Export Setup editor to set up CSV export at design time to export audit, alarm, and diagnostics information to CSV files at run time:

- When the trigger's value changes from zero to nonzero.
- If the trigger's initial value is nonzero when the application starts.

The CSV files will be saved to the specified path or paths. A CSV file name follows the format as YYYY_MM_DD_HH_mm_ss-<FileLabel>-TYPE.csv, where TYPE represents the type of information that could be ALARM, AUDIT, or DIAGNOSTICS. For example, an audit information CSV file name could be 2017_06_19_09_33_55-Batch001-AUDIT.csv.

Tip: | Storing more than 500 CSV files in a folder on an SD card may slow system performance. Use CVB Data Log Tamper Detection Utility to detect the integrity of the CSV file.
