CSViewer
CSViewer is a fast and free Windows desktop application for viewing and analyzing large delimited text and binary data files, such as CSV, TSV, Parquet, and QVD. It can load millions of rows in seconds and offers advanced filtering, instant profiling with aggregates, null counts, and outlier detection.

Export the filtered subset of rows into another file for sharing or use in another application. Convert data from one file format to another, e.g. from CSV to QVD.

Rons Data Stream
Rons Data Stream is a windows application designed to clean, or update, multiple data sources within seconds, whatever the size of the files, through the use of Cleaners.
"Cleaners" are made up of a list of operations that are selected from a broad list of Column, Row and Cell processing rules. They can be built, saved and applied to as many data sources as required, and re-used with as many Jobs as needed. The Preview window displays both the original data and a preview of the processed data. The result of each rule is therefore very clear and comprehensible.
"Jobs" contain all the detail needed for batch processing allowing 100's of data files to be processed in one go, making cleaning a whole directory an easy task.
Rons Data Stream handles tabular text formats (CSV, HMTL, XML files and tokenized formats), SQL and Parquet, from loading to converting. It can work individually or hand in hand with Rons Data Edit, adding power to both applications.
