Problem about exporting mysql query result into csv file

Question

I want to export mysql query result into csv file but I found there is something wrong with the format of csv file.

Input:

COMPANY AMOUNT VENDOR_NAME
    C1   70000           A
    C2    6000           A
    C3    2000           A
    C2   39000           B
    C3    4000           B
    C3   40000           C

Output:

VENDOR_NAME     C1     C2      C3    Total
          A  
             70000   6000    2000    78000
          B  
                 0  39000    4000    43000
          C  
                 0      0   40000    40000

In my output, the vendor name and other numbers are not in the same row... I don't know why. Maybe there are some mistakes in my code.

Here is my code.

CREATE TABLE test(
    COMPANY VARCHAR(50),
    AMOUNT DECIMAL(10,2),
    VENDOR_NAME VARCHAR(100)
);

LOAD DATA INFILE 'C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/try.csv' INTO TABLE test
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n'
IGNORE 1 LINES
(COMPANY,AMOUNT,VENDOR_NAME);

SELECT 'VENDOR_NAME','C1','C2','C3','Grand Total'
UNION ALL
SELECT 
    VENDOR_NAME,
    SUM(CASE
            WHEN COMPANY = 'C1' THEN AMOUNT
            ELSE 0
        END) AS C1,
    SUM(CASE
            WHEN COMPANY = 'C2' THEN AMOUNT
            ELSE 0
        END) AS C2,
    SUM(CASE
            WHEN COMPANY = 'C3' THEN AMOUNT
            ELSE 0
        END) AS C3,
    SUM(AMOUNT) AS Grand_Total

INTO OUTFILE 'C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/Result.csv'
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n'
FROM
    test
GROUP BY VENDOR_NAME;

I think you are not correctly defining the end of line characters. In Windows you may have to use:

LINES TERMINATED BY '\r\n' 

to read the file properly. It's seems like the VENDOR_NAME column has the the '\\r' characters at the end of the string.
