RAMADDA provides an interactive facility to transform CSV, JSON, XML or HTML files and create structured point data files and databases.

To start, upload the CSV/JSON/XML/HTML file into RAMADDA. Go to the Main Menu->View->Convert Data menu to see the conversion interface below. Here is the convert page for the below example.

A pipeline of commands are defined for manipulating the rows and columns of the source file. These commands can be on the same line or on multiple lines. If on multiple lines then the intermediate processing results of each line of commands is available. Prefix a line with "#" to comment out the line.

• The button allows you to add a new command. Once added you can edit the command in place or right click on the command to bring up the command editor dialog (see below).
• The button allows you to insert a reference to another file in RAMADDA for those c ommands (e.g., join) that require other files.
• The button allows you to specify settings -
• The button displays help.
• The Header, Table, Records, etc., buttons runs the commands and produces different output. The Save checkbox saves the command text when you run the commands so you can return to it later. The Do Commands checkbox applies the commands when you press one of the run buttons.
