3. Make sure Read variable names from the first row of data is selected. If the column headings do not conform to variable name rules, they are converted to valid variable names. The original column headings are saved as variable labels.
4. Select Remove leading spaces from string values.
5. Deselect Percentage of values that determine data type.
The string value {"no answer"} is now displayed in the cells that were system-missing. If there is no percentage of values parameter and the column contains a mix of data type, the variable is read as a string data type. All values are preserved, but numeric values are treated as string values.
6. Select (check) Percentage of values that determine data type to treat MaritalStatus as a numeric variable.
7. Click OK to read the Excel file.
The data now appear in the Data Editor, with the column headings used as variable names. Since variable names can't contain spaces, the spaces from the original column headings are removed. For example, the column heading {"Marital Status"} is converted to the variable MaritalStatus. The original column heading is retained as a variable label.
