Hi,

I have a txt file called a.txt which contain over 10,000 records and I would like to remove space before comma or after comma....like below:

The input (for example two record 00001,00002):
00001,client,card limited ,02292,N ,162:41 , 192, 94.589000, 0.000000, 94.589000, 0.000000,0 , 0, 0.000000, 0.000000, 0.000000, 0.000000,162:41 , 192, 94.589000, 0.000000, 94.589000, 0.000000,SIG ,SIN
00002,client2,hello Corporation Limited ,02507,N ,1594:23 , 193, 332.890000, 0.000000, 332.890000, 0.000000,0 , 0, 0.000000, 0.000000, 0.000000, 0.000000,1594:23 , 193, 332.890000, 0.000000, 332.890000, 0.000000,AUS ,AUD

output:
00001,client,card limited,02292,N,162:41,192,94.589000,0.000000,94.589000, 0.000000,0,0,0.000000,0.000000,0.000000,0.000000,162:41,192,94.589000, 0.000000,94.589000,0.000000,SIG,SIN
00002,client2,hello Corporation Limited,02507,N,1594:23,193,332.890000,0.000000,332.890000,0.000000,0 ,0,0.000000,0.000000,0.000000,0.000000,1594:23,193,332.890000,0.000000,332.890000,0.000000,AUS,AUD

condition:
- the 3nd field is a company name which may have space between each word. However, I just need to delete space at front and end split by ","
- the last field like record no#1 "SIN" may contain a few space after "SIN", I also need to delete it as well.

Please help and thanks!!!!!
