Error: Read text file, replace matching pattern, output to CSV file

Hi everyone,

I'm new to PowerShell. I'm trying to read a text file, find matching pattern ("NO RECORD") and replace it with ("NORECORD") then output the result to a new CSV file. However I didn't get the result I wanted

This is what I've done so far

Data file: sample_data.txt

DATE           AF         QD         QU
09/30/1920      NO RECORD       370.00  NO RECORD  
10/01/1920      NO RECORD       391.00     391.00
10/02/1920      NO RECORD       496.00    MISSING
10/03/1920      NO RECORD       660.00    MISSING
10/04/1920      NO RECORD       881.00    MISSING
10/05/1920      NO RECORD       660.00    MISSING
10/06/1920      NO RECORD       515.00    -9999
10/07/1920      NO RECORD       443.00    NO RECORD
10/08/1920      NO RECORD       443.00    MISSING
10/09/1920      NO RECORD       443.00    443.00
10/10/1920      NO RECORD       443.00    MISSING

Code:

$infile = "sample_data.txt"

$outfile = "test.csv"

Get-Content $infile | % {$_ -replace 'NO RECORD','NORECORD'} | Export-Csv -Path $outfile -NoTypeInformation

Output: in Excel

Any suggestion would be appreciated. Thanks!
