Convert EML to XLSX in Java & J2SE Applications

Convert Password Protected EML to XLSX

Accurately load and convert documents that are protected with a password within your Java based applications. The file format conversion API also supports rendering remote documents from different sources including S3, Blob, FTP, Stream, URL or a local disk.

Create new instance of Converter class and pass source document path
Instantiate the proper ConvertOptions class e.g. (PdfConvertOptions, WordProcessingConvertOptions, SpreadsheetConvertOptions etc.)
Call convert method of Converter class instance and pass filename for the converted document

Source Document Information Extraction

The documents information extraction feature not only allows getting the basic information about the source document file but it also supports extracting some valuable file-format specific information such as project start and end dates of a Microsoft Project file, any printing restrictions on a PDF document, list of folders enclosed in an Outlook data file etc.

Convert popular document file formats on different operating systems such as Windows, Linux or macOS while using development environments such as NetBeans, IntelliJ IDEA and Eclipse.

Convert Specific Word Pages to PDF in Java

Java document conversion API allows you to choose selected pages from the source document and accurately convert to the supported document format. The code example below shows how to convert the 1st and 4th pages of a Word document to the resultant PDF file.

Create a new instance of Converter class and load input (Word) document
Instantiate the proper ConvertOptions class e.g. (PdfConvertOptions, WordProcessingConvertOptions, SpreadsheetConvertOptions etc)
Set setPages property of the ConvertOptions instance and mention specific page number to be converted
Call convert method of Converter class instance and pass filename (PDF) for the converted document

Caching Converted Document Results

In some cases, the converted document size is bigger and it takes time to be converted. The document conversion library offers the caching feature to efficiently manage such situations and speed up the repetitive conversion process. Enable the ICache interface to work with custom cache implementation using the extension point and control the cache conversion, as you prefer.

The conversion result is saved to the local drive by default but any type of cache storage can be supported by implementing the appropriate interfaces such as Amazon S3, Dropbox, Google Drive, Windows Azure, Reddis or any other.

What is EML file format?

The EML file is a type of email message that includes both the message content and the email header information. It is an extension of the Mime (Multipurpose Internet Mail Extensions) format and is used in most email clients, including Microsoft Outlook and Mozilla Thunderbird. EML files are used to save an email message before it is sent and can also be used to archive emails. The EML file format is an XML-structured file that is used to store the header information, such as sender, recipient, subject line, and date, as well as the message content, such as body text, HTML, images, and attachments. The header information is stored in the header of the file and the content is stored in the body. The file is readable by both humans and computers, and can be opened in a text editor, such as Notepad or TextEdit. EML files are commonly used to transfer emails between different email systems. For example, when an email is sent from one email client to another, the email is usually saved as an EML file and then transferred over the internet. This ensures that the message is delivered properly. The EML file format is also used to store emails in an archive. For example, emails can be archived in an EML file and then later opened and read in any compatible email client. This makes it easy to keep emails organized and backed up. In addition to being used for email messages, the EML file format is also used by some applications to store log files, document files, and other types of files.

What is XLSX file format?

The XLSX file format is a widely used file format for storing spreadsheet data. It was introduced by Microsoft as part of their Microsoft Office suite, specifically for the Excel application. XLSX stands for Excel Open XML Spreadsheet. Unlike its predecessor, the XLS format, which was based on a proprietary binary file structure, XLSX is based on the Open XML file format.

XLSX files are structured as a collection of XML files compressed into a single ZIP archive. This XML-based structure allows for more efficient storage and faster data processing. XLSX files store data in a tabular format, with rows and columns that can contain text, numbers, formulas, and other types of data. They also support formatting options such as cell styles, fonts, colors, and conditional formatting.

One of the advantages of the XLSX format is its compatibility across different platforms and software applications. Many spreadsheet programs, including Microsoft Excel, Google Sheets, and LibreOffice Calc, can open and edit XLSX files. This makes it easy to share and collaborate on spreadsheet data with others, regardless of the software they are using.

XLSX files also offer features like data validation, filtering, sorting, and the ability to create charts and graphs based on the data. Additionally, XLSX files can contain multiple sheets within a single file, allowing users to organize and manage different sets of data within a single document.
