32Chapter 3• The original data type from Excel is preserved whenever possible, but since datatype is determined at the individual cell level in Excel and at the column (variable)level in SPSS, this isn’t always possible.• When SPSS encounters mixed data types in the same column, the variable isassigned the string data type; so, the variable Toys in this example is assignedthe string data type.READNAMES SubcommandThe READNAMES subcommand tells SPSS to treat the first row of the spreadsheet orspecified range as either variable names (ON) ordata(OFF). This subcommand willalways affect the way the Excel spreadsheet is read, even when it isn’t specified, sincethe default setting is ON.• With READNAMES=ON (or in the absence of this subcommand), if the first rowcontains data instead of column headings, SPSS will attempt to read the cells inthat row as variable names instead of as data—alphanumeric values will be usedto create variable names, numeric values will be ignored, and default variablenames will be assigned.• With READNAMES=OFF, ifthefirst row does, in fact, contain column headings orother alphanumeric text, then those column headings will be read as data values,and all of the variables will be assigned the string data type.Reading Multiple WorksheetsAn Excel file (workbook) can contain multiple worksheets, and you can read multipleworksheets from the same workbook by treating the Excel file as a database. Thisrequires an ODBC driver for Excel.
33GettingDataintoSPSSFigure 3-6Multiple worksheets in same workbookWhen reading multiple worksheets, you lose some of the flexibility available forreading individual worksheets:• You cannot specify cell ranges.• The first non-empty row of each worksheet should contain column labels thatwill be used as variable names.• Only basic data types—string and numeric—are preserved, and string variablesmay be set to an arbitrarily long width.ExampleIn this example, the first worksheet contains information about store location, and thesecond and third contain information for different departments. All three contain acolumn, Store Number, that uniquely identifies each store, so, the information in thethree sheets can be merged correctly regardless of the order in which the stores arelistedoneachworksheet.*readexcel2.sps.
