When I export data from ax to .csv file, the data comes with double quotes(e.g. "Test").
I don't want double quotes.
Can anyone help me in this.
That's how CSV is usually implemented. If you have to worry about it, it seems that what you use for import doesn't know how to handle CSV.
Maybe you should explain your problem in better detail.
Again, why do you want to get rid of them? They're important, as you see.
For example, this is a single field: "Amount 5,000.00".
Amount 5,000.0, on the other hand, is interpreted as two fields (assuming that you use comma as the separator: the first field is Amount 5, the second is 000.0.
You can't just remove quotes and expect everything to work. They're not there because somebody wanted to add more characters to the file; they're there for a reason.
If you don't want them in your output, use Find and Replace.
