I'm a beginner in salesforce and i hope this is the right place to ask.

I'm currently trying to update using data loader, in the Mapping Step, the column header always become one,


while it supposed to be,


i'm using comma delimited csv file.

I was wondering if you could help me find the problem.

Thank you

  • Does your comma delimited file have semi-colons between the headers rather than commas as that would not help or is that just for convenience while typing? Could you maybe post a screen shot of the actual .csv file header row and maybe a row of dummy sample data so that it would be easier to identify the problem.

Try to set default delimiter as comma, or you may have to upgrade data loader. If you are a windows user , here is the setting place.Region > Additional Setting > default list separator
