To convert tabs to commas in a text file when converting to CSV in PowerShell, you can use the following command:

How can I convert a large text file to CSV without crashing PowerShell?

You can convert a large text file to CSV without crashing PowerShell by using the following method:

1. Use the Get-Content cmdlet to read the text file line by line without loading the entire file into memory at once. This will prevent PowerShell from crashing due to memory overload.
2. Use a foreach loop to process each line of the text file and extract the necessary data.
3. Use the Add-Content cmdlet to write the extracted data to a CSV file.

Here is an example PowerShell script that demonstrates how to convert a large text file to CSV without crashing PowerShell:

# Specify the path to the input text file
$inputFile = "C:\path\to\input\file.txt"

# Specify the path to the output CSV file
$outputFile = "C:\path\to\output\file.csv"

# Open the output CSV file and write the header
Add-Content -Path $outputFile -Value "Column1,Column2,Column3"

# Read the input text file line by line and convert it to CSV
Get-Content $inputFile | ForEach-Object {
    $line = $_
    
    # Process each line and extract the necessary data
    $data = $line -split " "  # Split the line by space

    # Write the extracted data to the output CSV file
    Add-Content -Path $outputFile -Value "$($data[0]),$($data[1]),$($data[2])"
}

Replace the placeholder paths in the script with the actual paths to your input and output files. Additionally, modify the data extraction logic based on the format of your text file.

By using the Get-Content cmdlet to read the text file line by line and processing each line individually, you can convert a large text file to CSV without crashing PowerShell.

How do I specify delimiter when converting a text file to CSV in PowerShell?

When converting a text file to CSV in PowerShell, you can use the ConvertFrom-CSV cmdlet and specify the delimiter using the -Delimiter parameter. Here's an example of how you can do it:

1

Import-Csv -Path "C:\path\to\your\file.txt" -Delimiter ";" | Export-Csv -Path "C:\path\to\your\output.csv" -NoTypeInformation

In this example, the delimiter is specified as ;. You can change it to any other character that is used as a delimiter in your text file.
