1 、 DataWrangler

Stanford University Visualization Group (SUVG) designed a web-based service for you to clean up and rearrange data. Click on a row or column and DataWrangler will pop up the suggested change. For example, if you click on a blank line, some suggestions pop up, delete or delete blank lines. Its text editing is very cooool.

2 、 Google Refine

Google Refine . After the user runs the application on the computer, it can be accessed through the browser. The main function of this thing is to help users organize data, and the following demo video works very well: the user downloads a CSV file, but the same attribute in the same column can be written in many ways: full name, abbreviation, followed by spaces, singular and plural formats.

For large-scale data, you can use Google Fusion Tables to create a filter to display the data you care about, and after processing, you can export it to a csv file.

The powerful ability of Google Fusion Tables to deal with large amounts of data and the ability to freely add different spatial views may worry traditional database manufacturers of Oracle,IBM and Microsoft that Google will strongly intervene in the database market in the future.
