While exporting from Cyrstal Report to CSV, data is showing null

Hi All,

It first runs crystal report and records are fetched successfully. And then records are exported to following 2 formats.

1. Excel Format
2. CSV Format

Report is exported to excel successfully, but when exported to csv then have some problem. For Instance if report is having 30,000 records, then after export excel sheet shows 30,000 records but csv file shows 26,000 records and rest of the records are not shown. and in csv on line no 26,001 half recrod is exported and for rest of half it shows null.

Its very urgent and any help will be highly appreciated.

Regards,
