Hi 

I have a exel table (xlsx) with Date column where some values are text 'NULL' while some values have date in format mmddyy.

I'm able to import this data in sas eg thr' import wizard only with defining field attributes as date and not any other method.

the import wizard creates sas program which i can not use 

so everytime i have to use same folder and location to immport and i have many files

which is a lot of manual wok 

can i reduce manual work of importing xlsx files with mixed columns to a simple sas program which i can modify and use for other files too.

 

plz inform if i'm missing something. 

Thanks in advance

What do you mean when you say "I cannot use"? When the text NULL is translated to a missing value in SAS that would be a valid result. Could you share that code and its log? 

 

Otherwise you would have to create a character variable from your date and do some postprocessing like

 

if datevar_char=' NULL' then 
   datevar_num=.;
else
   datevar_num=input(datevar_char, anydtdte.);

The informat ANYDTDTE could be replaced with any informat that works for your specific data.

 

Hope this helps,

- Jan.

table i am using is Book1

R131/13/2000NULL

R151/15/2000NULL

and the output i am getting is for data step >at

EmployeeCode DateofJoin DateOfRelieving
PK . .

output for proc import is (whre dates are from 01/01/1900 hence i can not do post processing after import.)

R1 01/01/2000 NULL

R13 01/13/2000 NULL
R14 01/14/2000 41197
R15 01/15/2000 NULL

 

and expected output is

Did you assign a FORMAT to DateOfRelieving?

 

I would expect to see a Format DateOfRelieving  mmddyy10.; statement.

In short not easily. SAS doesn't have an easy way to specify the field types from an Excel. Your also compounded by using EG which may mean your files have to be uploaded to a server before importing them in an automated fashion. 

 

In the EG wizard you can manually change the field type.

COMMENTS

I believe it is possible to create an excel sheet where
the meta data on a cell type(format) does not
match text in the cell. Manually editing
a cell that has a date format does not change the underlying
meta data(type). Just type ROGER in a date formatted cell.
In this case I think you would
need to programatically create an image file and use
the SAS tesseract tool to convert the image to text.
Python OpenxL can extract the cell format(c.type)
