Understanding pst and csv file formats
PST (Personal Storage Table) is a proprietary file format used by Microsoft Outlook to store copies of messages, calendar events, and other items. It is commonly used for email archiving and backup. CSV (Comma-Separated Values) is a widely used plain text format for storing tabular data, such as spreadsheets or databases, where each line represents a data record and fields are separated by commas.
Why convert pst to csv?
Converting a PST file to CSV format allows you to extract email data, contacts, or calendar information from Outlook and use it in spreadsheet applications like Microsoft Excel or Google Sheets. This is useful for data analysis, migration, or sharing information in a universally accessible format.
How to convert pst to csv
There is no direct built-in feature in Outlook to export all PST contents to CSV, but you can export specific folders (like Contacts or Emails) to CSV. Here’s how to do it using Microsoft Outlook:
- Open Microsoft Outlook and go to File → Open & Export → Import/Export.
- Select Export to a file and click Next.
- Choose Comma Separated Values and click Next.
- Select the folder you want to export (e.g., Inbox, Contacts).
- Choose the destination and filename for your CSV file.
- Click Finish to complete the export.
If you need to convert entire PST files or multiple folders, consider using third-party tools.
