Method 1: Create a spreadsheet
Create a new spreadsheet using a program such as Excel or Google Spreadsheet in the format described here: http://support.datacracker.com/knowledgebase/articles/292381-importing-excel-spreadsheets-or-csv-files
Your question names should be in the first row of the spreadsheet. The responses to the questions should be below the variable, starting from the second row. Each person's response should be in a separate row.
Once finished entering your data, export the spreadsheet as an Excel .xlsx file (or .csv file) and save it to your computer.
You can now upload the Excel file to DataCracker to create your report. Go to your My Reports page and click + Upload data. The setup wizard will appear with the title Where is your data from? - select Other. Click the Upload button that appears, and select the Excel file from your computer.
Method 2: Use a data collection program
Create a questionnaire in an online data collection program, such as SurveyMonkey, and then enter your data into this as if completing the questionnaire as a respondent. Make sure you do this using a program that can export an SPSS Data File (.sav).
This approach is generally the best in terms of getting a well-structured data file with rich metadata.
Method 3: Scanning and OCR
Documents can be scanned and optical character recognition (OCR) used to capture open-ended responses. This process is usually very complex to implement and is inadvisable except with huge studies.
