1.0 SPSS commands in this unit
get data | used to read in data in different formats, such as Excel and comma separated values (.csv) |
data list | used to read in data that are in fixed or list format |
list | lists the data in the output window |
get file | used to read in data that are in an SPSS data file |
2.0 Demonstration and explanation
In this unit we will show several ways of getting data into SPSS.
2.1 Reading in an Excel file
We will start with inputting an Excel file. The variable names are on the first line of the Excel file.
|
* read in an excel (.xls) file. get data /type=xls /file = 'c:\temp\hs0.xls' /sheet=name 'hs0' /readnames=on. |
2.2 Reading in a comma-separated-values text file
A comma-separated-values (.csv) format data file is a text data file and can be read in as follows. The variable names are on the first line of our data file hs0.csv. The same procedure will also work with tab-delimited data files.
|
* read in a text file. get data /type = txt /file = 'c:\temp\hs0.csv' /delimiters = "," /firstcase = 2 /variables = gender f1.0 id f3.0 race f1.0 ses f1.0 schtype f1.0 prog a10 read f2.0 write f2.0 math f2.0 science f2.0 socst f2.0. execute. |
2.3 Reading in an ASCII fixed-format text file
The other type of commonly used ASCII data format is fixed format. It always requires a codebook to specify which column corresponds to which variable. Here is small example of this type of data with a codebook. One way of inputting this type of data is through the syntax editor.

variable name column number id 1-2 a1 3-4 t1 5-6 gender 7 a2 8-9 t2 10-11 tgender 12
You will need to open a new SPSS syntax editor into which you can type the following code. Remember that each command in SPSS must end in a period (.).
|
data list fixed file="c:\temp\schdat.fix" / id 1-2 a1 3-4 t1 5-6 gender 7 a2 8-9 t2 10-11 tgender 12. list /cases = from 1 to 10. |
2.4 Inputting data via the syntax editor
Using syntax editor, we can also input data directly. You can copy and paste the syntax below to the syntax editor and run it. Notice the difference in syntax between a numeric variable and a character variable.
|
data list list /id (f3) female (f1) race (f1) ses (f1) schtype (a3) prog (f1) read (f2) write (f2) math (f2) science (f2) socst (f2). begin data. 147 1 1 3 pub 1 47 62 53 53 61 108 0 1 2 pub 2 34 33 41 36 36 18 0 3 2 pub 3 50 33 49 44 36 153 0 1 2 pub 3 39 31 40 39 51 50 0 2 2 pub 2 50 59 42 53 61 51 1 2 1 pub 2 42 36 42 31 39 102 0 1 1 pub 1 52 41 51 53 56 57 1 1 2 pub 1 71 65 72 66 56 160 1 1 2 pub 1 55 65 55 50 61 136 0 1 2 pub 1 65 59 70 63 51 end data. |
2.5 Opening an SPSS data file
Last but not least, here is how to open an SPSS data file.
|
* how to open an SPSS data file. get file 'c:\temp\hs0.sav'. |
If you are using syntax, you will want to have the method of opening the data at the top of your syntax file. Please note that SPSS can have multiple data files open at once, and your syntax will operate on the active data set.
