A comma-separated value is a file format that stores your data in the.csv extension. The data format is in tabular form and includes your contact information in numbers and names in a row-column manner. Which is easily accessed by a spreadsheet application like OpenOffice, MS Excel, or Google Sheets. I give you the best solution regarding your query: use an automated OSTtoPSTAPP CSV to VCF exporter. The program is easy to use with its incredible functions. The scanning mechanism is much faster than another tool that scans all your contact information, such as your last name, first name, emails, and home addresses, within a few seconds. The application allows every user to use the mapping function to customize their CSV format files without any interruptions and keeps putting all converted VCF format files in a safer location on the user's desktop. The utility interface is user-friendly and easy to use without requiring any technical help, and it supports all the latest Windows operating systems.
