EML to CSV: Bulk Convert .EML Email Files To a List

Professionals who regularly work with E-Mail understand the importance of being able to batch convert a large number of .eml email files to a text format. Whether you need an easily searchable text version of E-Mails, or if you just need to capture basic E-Mail header information in a text format,  EmlViewer Pro can help. This capability is included with every copy of EmlViewer Pro.

How to Convert .Eml to CSV

To follow along with this tutorial, download a free trial of EmlViewer Pro. The trial will allow you to export up to 50 E-Mails per export operation.  This restriction is of course removed from the registered version of the software.

When EmlViewer Pro first starts, use the folder explorer on your left hand side to select the folder where your .eml files are stored.  EmlViewer Pro will then read those E-Mail files into an organized list.

If you want to convert all of the E-Mails in the list to .csv/text, you can select them all for export by typing Ctrol-A.  Selected E-Mails will be highlighted in blue.

Exporting .eml into .csv format lets you then import E-Mails into Microsoft Excel.

Next select the Export tab.
From the drop down list, choose the CSV export profile, as shown in the image below.

The last step is to click the “Export” button to begin the operation.  EmlViewer Pro will proceed with saving the select .eml E-Mails into a text-based Comma Separated Values (CSV) file. The .CSV file will be written to a folder location that you indicate.

Clicking on the .CSV file will cause it to open in your default spreadsheet application. In the image below, the CSV file has been opened in Microsoft Office Excel 2013.

The E-Mail content has now been organized into columns that include the following fields:
From, Subject, Date, To, CC, Message Body, file attachment information, and a link to the original .eml file.

These columns can re-arranged or deleted, searched or otherwise manipulated.

While the trial version of EmlViewer Pro restricts export operations to 50 E-Mails, there is no limited to the number of .Eml files that may be converted to .CSV in the registered version.

Viewing Email Property Values and Transport Header in .EML Files with EmlViewer Pro

EmlViewer Pro is a versatile tool for managing .eml and .msg emails Microsoft Windows. With EmlViewer Pro, you view, search, print and convert email messages.

EmlViewer Pro makes email metadata accessible, including internet transport header information embedded within an email message. This information is often hard or impossible to access in a standard email client.

Email transport header data and properties data is useful for verifying the authenticity of an email message. It can show the server path that the message took on it’s way to the destination inbox.  Note that if the .eml file you are looking at was created locally, there will be no transport header; only emails that have traversed the internet will contain transport header information.

To access transport header details for a .eml file, first open the message in EmlViewer Pro, then go to Mail>Properties.
