Interactive Web Tool To Clean Data for Analysis and Visualization

I recently came across a free web interactive tool by Stanford Visualization Group called DataWrangler. This tool is great if you are downloading public data sets or have data sets of your own and want to clean them up before putting them into a data anaylsis program or data visualization program.What’s great about this tool is that DataWrangler suggests different operations to perform to clean up the data or you can manipulate the operations to reflect how you want to data cleaned up. Some of the operations also give you a preview of what the data will look like before you commit to that operation. You can export the cleaned up data for DataWrangler in Python or Java or can choose CSV, TSV, Row-Oriented JSON, Column-Oriented JSON, or Lookup Table. If you want to try out this tool, click on the link below to get started: http://vis.stanford.edu/wrangler/
