You would have to tell use explicitly what values you change from and too. But unless you take extra steps that almost no one does if your original value was "2208,03" and you change the value to anything that might be interpreted as a number such as 220,803 then Excel changed the CELL to numeric. And very likely on file>save as>CSV (you did do this correct?) the value came out as ,220803, no quotes or even worse ,220,803, no quotes and now a different field.
Either edit with text editor, OR (sometimes this works, sometimes not) set the entire column in Excel as text before making any edit.
OR use program code in a data step:
If value='2208,03' <possibly with other qualifier such as: and ID='abc'> then value='220,803';
Also if you have multiple files with the same structure you would be much better off writing a data step because Proc Import guesses variable length and type every single time and your data sets may not be compatible.
Note that Proc Import with CSV will write a data step to the log that you can copy, paste into the editor, modify and save. Then you change the infile and output data set to get the desired result.
You also should use guessingrows= with a moderately large value or the key word MAX to have better compatibility on variable length when importing CSV or other delimited files.
