Screen shot showing CSV selected a export format.

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.

Converting Emails from .EML to .HTML Files.

A .eml file is an individual email message that has been moved outside of an email client, such as Mozilla Thunderbird. EML files may contain pictures, file attachments, email metadata, and more.

Its very common to receive email messages that are formatted either as Text (.TXT) or HTML files. Embedding HTML in emails lets the sender mark up the text. They can add formatting, titles, colors, images and logos to their email messages.

In an earlier article, we described how to convert .eml to text files with EmlViewer Pro (also known as PstViewer Pro), the email https://www.emlviewer.net/2013/08/19/how-to-convert-multiple-eml-email-into-text-files/viewer software for Windows that lets you discover and convert email messages.  If plain old text files are too boring for you, let us show you how to convert .eml email files directly into HTML documents. You could even post them to your web server, if you like, for the entire internet to see.

Converting .EML to .HTML Files

Saving a .eml email file as html file will save the HTML code to a .html file.  Instead of having all of the elements contained in a single .eml file, an email converted from .eml to .html will be broken apart, just like a regular web page. The individual elements will be stored as separate files that are linked from the resulting .html page. Any embedded elements, like pictures, will be stored in a folder.

Converting .eml files to .html is useful if you want to preserve the email content, but also want easy access to embedded images or  file attachments.

Although we are describing how to convert .eml to .html, this same process can be used with EmlViewer Pro to create html files from emails stored in .msg, .pst, .ost and .mht files. You can convert one email to html, or bulk convert thousands of emails to .html.

Eml Viewer Pro

If you would like to follow along with the step by step instructions, download a 15 day free trial of EmlViewer Pro software (also known as PstViewer Pro)for Microsoft Windows by Encryptomatic LLC.  EmlViewer Pro is also known as PstViewer Pro. At one time EmlViewer Pro and PstViewer Pro were separate products, but they have recently been combined into a single more powerful product able to process many different email formats.

Step 1 Start EmlViewer Pro. Using the folder explorer on the left side of the screen, select the folder containing your .Eml Files. The emails will be viewable in the EmlViewer Pro mail list.

Step 2  Select the Eml files you want to convert to HTML.  Selected files will appear highlighted in the mail list.

Step 3  Select the target export format “HTML”

Step 4  Click the “Export” button to begin the export process.

The Eml files will now be converted into Html.  Lets take a look at the folder and see how the files are organized.

Notice that the folder contains .html files that use the email Subject line as the file name. The image elements for emails that contain them will be placed in a sub folder, which will share the same name as the html file. Folder organization keeps the email elements (images and file attachments) from being mingled with other emails.

To view the email as a HTML page, click on it, and Windows will open it in your web browser,
