reading in json data

here is the error when I read this data. there are no observations. Why ?


 filename data '\\kashmir\BFD\sample_json1_may26.txt';

6300  data datatest;
6301   infile data lrecl = 32000 truncover scanover;
6302   input @'"text": "' text $255. @'"from_user": "' from_user $255. @'"created_at": "' created_at
6302! $255. ;
6303  /*text = substr(text,1,index(text,'",')-2); from_user = substr( from_user,1,index(
6303! from_user,'",')-2);
6304  created_at = substr(created_at,1,index(created_at,'",')-2); run;
6305    */

NOTE: The infile DATA is:
      RECFM=V,LRECL=32000,File Size (bytes)=1989,
      Last Modified=26May2017:12:28:24,

Re: reading in json data

Without actually seeing the data file here is something to check:


When using the Input @'text value' then the value you supply in the code must be exactly as it appears in the source file.

If the file has "Text value" then it does not match 'text value'


Also the "Minimum record length was 1" may indicate you don't even want to attempt the read the first line. Perhaps add "firstobs=2" to accomplish that.

If you're using SAS 9.4 you might find the JSON library engine much easier to use than trying to parse it yourself. The details are here
