The first step to build an app is preparing the spreadsheet. It's not difficult, just put column headers in the first row. Qrimp uses the header row in your spreadsheet for column names in your tables and field names on forms. Include multiple data sets on sheets and Qrimp will import each sheet as a new table.
Qrimp can build any kind of web based database application, but for our example, we are going to build a Federal Campaign Contributions Manager using data we got from the FEC. You can download this data yourself from the FEC Website.
