You can update data in Protobi as often as you need. For example, if your survey is in field, you can upload data every day as fielding progresses.
Data in Protobi is independent of the view, so you can update data without resetting your charts and organization.
To update data, go to the Project settings page and select the Data tab.
Find (or create) the data table to update, and drag a data file to the Upload box (or press the box and select a file from the system dialog).
Protobi currently accepts SPSS (*.sav) or CSV (*.csv) data files. If your file is in Excel, use Save As... and select type "Comma Separated Values *.csv" in the dialog. If CSV, Protobi assumes the first row is column names and each row is a respondent.
Update any dependent processes
If your project has a data process (green square icon), and that process depends on a file you just refreshed, you may need to re-run the process.
In the data process, press the "Edit/Run" button to get to the process "Pre-Calculate" page. Once there, press the grey "Run" button. The data process will then be applied to the newly updated data.
