Currently, our online system accepts the following file formats:
a) Plain text (.txt)
b) Comma Separated Value (.csv)
c) Microsoft Excel Spreadsheets (.xls or .xlsx)
d) OpenOffice Spreadsheets (.ods)
Uploading, downloading and integrating these formats are a breeze.
If you have any other file format, you may need to convert it to .csv or .txt file. To prepare csv file from other spreadsheet formats, open your spreadsheet application and save file as Text csv (.csv). Or simply create a text file with .csv OR .txt extension. File must list emails in single column.
