Can I select the format of my output file?

Yes, you can select from .csv, .xls, or.txt for your Optimizer output file format just prior to downloading your file. It is important to note that the different file formats have different corresponding file sizes.

.xls � 65k record limit
.csv � 65k record limit
.txt � no limit

If your file contains more than 65k records, D&B recommends either opening as a .txt document, or splitting your output between multiple files.
