比较Powershell中的2个CSV文件并输出差异

Question

Following Problem:

We have 2 csv files with a few differences in them. Now we want to compare these two via a unique number that is already included in both files and output the rows where a difference was found (anywhere in that row) into a seperate csv with the header included. All that should be done in Powershell. It is important that the output file has the exact same formating as the files we are comparing. Also our csv files have a total of ~90 Cells in width and around ~1000 rows.

Does anyone have an idea how this could work?

Answer 1

you can try to import both csv files and compare it with Compare-Object like this:

$CSV1 = "Path to CSV1"
$CSV2 = "Path to CSV2"

$ImportedCSV1 = Import-Csv $CSV1
$ImportedCSV2 = Import-Csv $CSV2

Compare-Object -ReferenceObject $CSV1 -DifferenceObject $CSV2
