In addition to that, it also shares the possible reasons behind this export, the prerequisites for each method, the pros and cons of the manual and professional solutions, frequently asked queries, and an unbiased conclusion to convert PST file to CSV. So, without any further ado, let’s begin with the main drill.

Why Users Need to Convert PST to CSV?

Many people convert PST  to CSV to make Outlook data easy to handle, view, import, or share. In such a case, CSV files are compatible with many applications, including Microsoft Excel, Google Sheets, and other such platforms. This makes accessing the data in an organized, tabular, and readable way possible.

Here are the main reasons to convert Outlook PST file to CSV:

  • In most of the cases, users convert PST contacts to CSV so that they can easily import data into CRM.
  • Since CSV has rows and columns like structure, it makes navigation, sorting, filtering, etc. easier than any other file format.
  • Apart from this, many of the users convert Outlook PST to CSV for backup or long-term future-use purposes.
  • CSV files can be easily integrated and supported in data-driven analysis and decision-making.

How to Convert PST to CSV With Outlook Classic?

Outlook Classic gives an in-built option to import or export data safely. Therefore, using that, a user can easily convert Outlook PST to CSV format with ease and efficiency. However, there are some limitations as well in this method, so make sure you check that out too. The detailed steps for this solution are as follows:

  1. Open the Outlook application on your computer.
  2. Go to the “File” option, choose “Open & Export,” and click the “Import/Export” button.
    select import and export
  3. After that, select the “Export to a file” option and hit “Next.”
    export to a file
  4. Then, choose “Comma Separated Values” option and click on “Next” again.
    select csv
  5. Now, select the “Folder” including inbox, contacts, calendars, etc. that you want to export in CSV format, and select the “Next” button.
    select folder
  6. Further, click on the “Browse” button to select the saving path on your computer, and hit the “Next” button.

  7. After this, click on Map Custom Fields to cross-check the Outlook contact and CSV fields. It includes First Name, Phone Number, Last Name, Suffix, Job, Title, and so on.
    field mapping
  8. Once done, click on the Finish button and let the process of conversion complete.

  9. Done! With the use of this built-in method, you can convert PST to CSV with Outlook itself.

Alert: Outlook Classic only supports one folder at a time to convert or export the data in another format. This makes it an inefficient solution for those who have bulk data to convert in CSV format. In addition to that, this method works great in converting Outlook PST contacts only to CSV format since other data, such as emails, do not retain the same after conversion. Thus, it does not support attributes like attachments, images, categories, and more of an Outlook PST email when converted to CSV using this method only. Therefore, to convert more than contacts, using a dedicated PST to CSV converter is the ultimate solution.

How to Convert PST to CSV With Outlook New?

If you are a new Outlook user and want to convert PST files to CSV, then you must learn that New Outlook does not fully support exporting local PST contacts and calendars to other formats.

Therefore, to get complete access and control over PST export to CSV, the user must have Outlook Classic installed and actively working in the background.

  1. Thus, open Outlook New and click on File.
  2. Now, click on the Open and Export option.
  3. After this, from the left panel, select Data Files and then choose the Export option.
  4. Further, click on Get Started to select the Outlook PST data.
  5. Moreover, follow the instructions to choose Comma Separated Value as the saving option, saving destination, and mapping option.

Alert: In most of the cases, this option is greyed out and requires a Microsoft 365 subscription to convert PST to CSV with Outlook New. In such a case, the ideal step is to switch to Outlook Classic for export purposes and then get back to the New Outlook once done.

Convert Outlook PST to CSV Using PowerShell

This is one of the technical ways to convert PST files to CSV format. In this, the user has to write a script to proceed with the conversion. The brief steps for the same are as follows:

  1. Open Windows PowerShell on your desktop PC.
  2. Now, simply copy and paste the code below into PowerShell.
    # Path to PST file
    $pstPath = "F:\Outlook Testing\Robert.pst"
    # CSV output path
    $csvPath = "F:\Output\Robert.csv"
    # Create Outlook COM object
    $outlook = New-Object -ComObject Outlook.Application
    $namespace = $outlook.GetNamespace("MAPI")
    # Add PST file to session
    $namespace.AddStore($pstPath)
    $pst = $namespace.Folders | Where-Object {$_.FilePath -eq $pstPath}
    # Create array to store email data
    $emails = @()
    # Loop through all folders in PST
    function Process-Folder($folder) {
    foreach ($item in $folder.Items) {
    if ($item -is [__ComObject]) {
    try {
    $emails += [PSCustomObject]@{
    Subject     = $item.Subject
    Sender      = $item.SenderName
    Received    = $item.ReceivedTime
    Body        = $item.Body
    }
    } catch {}
    }
    }
    foreach ($subfolder in $folder.Folders) {
    Process-Folder $subfolder
    }
    }
    Process-Folder $pst
    # Export to CSV
    $emails | Export-Csv -Path $csvPath -NoTypeInformation
    # Remove PST from session
    $namespace.RemoveStore($pst)
  3. Before using this code, change the path location as per your computer location in these areas.
    $pstPath = "C:\Path\To\Your\File.pst"
    $csvPath = "C:\Path\To\Output\emails.csv"
  4. Done! Your PST files are converted to CSV using PowerShell.

Alert: This PowerShell script supports only the PST email messages and does not work well for PST Contact and Calendars. Trying it to convert more than PST emails might give error, altered results, or empty output.

Common Drawbacks of Manual Methods

  • Users must have technical knowledge of Microsoft Outlook and Windows PowerShell to use the conventional ways.
  • Using Outlook to convert PST to CSV for large PST files and multiple folders is time-consuming and might freeze the computer system.
  • Users need to select folders individually, which makes it inconvenient in case of nested folders.
  • Non-tech users might face some unknown challenges while running and setting up PowerShell scripts.
  • A large PST file will slow the script, and your computer’s storage will start getting full.
  • These methods are very prone to error and can result in permanent data loss.

These are the major unavoidable drawbacks of the manual workaround that every user should know before using them.
