We have a prototype ready to test at http://geomancer.datamade.us/

The wizard takes you through 4 steps:
 1. Upload your spreadsheet
 2. Select which column with geography data you want to match data on
 3. Choose what data you want to append. We are starting with a collection of data from [censusreporter.org](http://censusreporter.org):
  * Population percentage by race
  * Group quarters population
  * Unmarried-partner households by sex of partner
  * Educational attainment
  * Median household income
  * Median value owner occupied housing
  * Place of birth (foreign-born population)
  * Per capita income
  * Median age
  * Total population
 4. Wait for the new data to be fetched, matched and merged and then download your original spreadsheet with the additional columns added.

There are still some kinks to work out, including form validation, handling ambiguous geographies, and filling in more context for each step. We'll open these up as separate issues as we get to them.
