I can't upload contacts into mysurveylab

If you can't upload a list of contacts into mysurveylab, please check :

  1. if your file does contain blank lines
  2. if your file contain special characters on the of each line or inside contacts

If your file contains blank lines please delete them. To do it you can use MS Excel. Upload your file into Excel, sort it and then copy only lines with contacts. Then paste copied lines into a new text file.
