Ron's Data Cleanser is a free utility that permits you to automize the cleaning of data files as well as source jobs.

Ron's Data Cleanser is designed to update and clean a data source (for example, CSV files) through the use of Cleaners, making the process more efficient. Cleaners are made up of a list of operations that can be built, saved, and applied to a data source as required. The preview window makes the comparison of the original data with the processed data very clear. Ron's Data Cleanser also includes a batch processing capability. This allows 100's of data files to be processed in seconds, making cleaning a whole directory fast and efficient.

Using Ron's Data Cleanser to create operating rules (the Cleaner) is simple - define the source, format, and output (the Job), combine and run.

Jobs: set up of data sources, formats and destinations
Jobs files can be stored with the data (if the data is in a directory), or separately if needed, and run at the click of a button or from the command line.
