I just tried importing a .CSV file to a Data Extension (there are only 3 rows as I'm doing a test), but I keep getting an error. My CSV files have the right headers that can be mapped, so I'm not sure what went wrong.


  Field Not Found: 1
  Required Field: 2

This is what is shown in the accompanying text file (anonymised):

Row Number  Error Number  Error Code  Error Details  Row Data
0  24032293090  FieldNotFound  Email   
0  24032293091  RequiredField  email  [redacted Casesafe ID][Ms.][Jane][Doe][[email protected]]
1  24032293092  RequiredField  email  [redacted Casesafe ID][Ms.][Jane][Smith][[email protected]]

Does anyone know what the FieldNotFound and RequiredField errors are and how I can fix my CSV file to successfully import the contacts? Thank you!

  • Are you using the correct delimiter in the import (e.g. comma vs semicolon)? Oct 7, 2021 at 10:11
  • I've checked that the delimiter is a comma and not a semicolon - is that the right delimiter?

  • also would check on using text qualified if possible as your issue could be a comma in one of your fields is being read as a delimiter and not as part of the text field - which can blow up your file. Oct 8, 2021 at 11:49

The problem is probably with a delimiter in the Data Extract that you set up OR what delimiter Import Activity is expecting, so check those 2 places.

Usually, it would be enough to use a pipe or tab delimiter to properly split the values, however, if you have a really extensive file, you can use a more "powerful" delimiter as "☺" for example (in other words, the character that is not present in the file).

Regarding the errors:

  1. Field Not Found: 1 - The first one says that it cannot find the Email field.
  2. Required Field: 2 - Some of your non-nullable fields in the receiving Data Extension do not get the value from those 2 rows. Again, a proper delimiter should solve it.

Here is an official article about Import File Activity errors (yet not all of them).

  • Thanks for the answer! I imported a .CSV file and checked that the delimiters were all commas in the file, and on importing I also selected comma as the delimiter. I will give pipe and tab delimiters a go.

I had similar case, and the problem was a field name with space behind like this: "field name "
