The Data Comparison Tool. Compare data from files (Excel, csv and txt) and Queries (MS-SQL, Oracle, Amazon Redshift, MySQL, and more...) Comparing data from files and queries has never been easier. Don't drown under hours of tutorials, spreadsheets and formulas that will be good for only ONE time, let the clicks do the work and compare A and B without learning how to code! If any of these situations prevents you to spend your time on things that require your actual talent, then this is the software for you (disclaimer, reading the list can cause pain): Reports migration, data differences between stages, data mismatch, "Row count match but numbers don't","this query works different in this other Engine/DB", "001 <> 1" (or vice versa), find missing data, "that report was different X days ago", "I have to compare this again", etc.
