Users with a Google account, for example one from a Gmail account, can access Google Fusion Tables right away. Each user gets 250 Megabytes of storage space on the Google servers and the ability to upload data that cannot exceed 100 Megabytes per data set. Currently only Microsoft Excel (xls) and comma separated value (csv) files are supported by the Google data management product. Uploaded data can then be shared with collaborators with the additional option to share only part of the data with different collaborators.

The data can be visualized by the user in various ways including the default table form, pie charts, bars or intensity maps among other forms of visualization.

It is furthermore possible to edit the data at hand or to merge it with another set of data. Merging tables could not be easier. All that needs to be done is to select the two spreadsheets that should be merged and which columns to use for matching data across the two tables.

Google Fusion Tables is an easy to use data management service that comes with an interesting set of features that the developers plan to expand in the future based on user feedback.
