import csv file into mysql with custom data change
What's below works for your data - be careful of any variation in the field width - that's why delimited files are better - csv, or better still, if you can get it, pipe-delimited (|). It also successfully deals with the header line.

I did the following:

My code will do for both MD5 and SHA2 passwords - uncomment the relevant bits.

CREATE TABLE my_user
(
  user_id int not null auto_increment primary key, 
  username varchar(11), 
  p_word varchar(64), -- VARCHAR(32) for MD5
  e_mail varchar(75)
);


using a sample based on your data (users.csv)

$&gt; more users.csv;
Username   Password   Email
test123    123        test@foobar.com
test456    567        sdfsd@blah.com
$&gt; 


And then after some Googling, I came up with this

LOAD DATA 
INFILE '/mysql/mdb5.5/inst/users.csv'
INTO TABLE my_user
IGNORE 1 LINES
(@row)
SET username = TRIM(SUBSTR(@row,  1, 11)),
    -- p_word   = MD5(TRIM(SUBSTR(@row, 12, 22))), 
    p_word = SHA2(TRIM(SUBSTR(@row, 12, 11)), 256),
    e_mail  = TRIM(SUBSTR(@row, 23, 80))
;


And voilà!

MariaDB [test]&gt; select * from my_user;
