Welcome to Data Picker and Data Merger!
Putting data together is the first step for any data analysis. You must have experienced the pain of copying and pasting within and between spreadsheets. I have developed two small Java applications: DataPicker and DataMerger, which can save you from the tedious, boring, and time-consuming processes of copying and pasting.
Both Data Picker and Data Merger are safe, handy, easy-to-use, light-weight, free software.
