Data is stored and displayed to users in table format in worksheet and can span numeric values, text data, formulas, external data connections, images, and charts. Applications like Microsoft Excel lets you export workbook data to several different formats including &lt;a href="https://www.aspose.info/pdf/"&gt;PDF&lt;/a&gt;, &lt;a href="https://www.aspose.info/spreadsheet/csv/"&gt;CSV&lt;/a&gt;, &lt;a href="https://www.aspose.info/spreadsheet/xlsx/"&gt;XLSX&lt;/a&gt;, &lt;a href="https://www.aspose.info/word-processing/txt/"&gt;TXT&lt;/a&gt;, &lt;a href="https://www.aspose.info/web/html/"&gt;HTML&lt;/a&gt;, &lt;a href="https://www.aspose.info/page-description-language/xps/"&gt;XPS&lt;/a&gt;, and several others. The XLS file format was replaced with a more open and structured format, XLSX, with the release of Microsoft Excel 2007. The latest versions still provide support for creating and reading XLS files, though XLSX is the first choice of use now.&lt;/p&gt;</description></item><item><title>What is an _XLSX file?</title><link>https://www.aspose.info/spreadsheet/_xlsx/</link><pubDate>Tue, 10 Dec 2019 00:00:00 +0000</pubDate><guid>https://www.aspose.info/spreadsheet/_xlsx/</guid><description>&lt;h2 id="what-is-a-_xlsx-file"&gt;What is a _XLSX file?&lt;a class="anchor" href="#what-is-a-_xlsx-file" aria-label="Copy link to this section"&gt;&lt;/a&gt;&lt;/h2&gt;&#10;&lt;p&gt;A file with ._xlsx extension is actually an &lt;a href="https://www.aspose.info/spreadsheet/xlsx/"&gt;XLSX&lt;/a&gt; file that is renamed by some other application. This can happen in certain cases when the filename contains a . at the end of the file name. The _XLSX files can be opeend in Microsoft Excel similar to the XLSX files by again renaming these to .xlsx extension.&lt;/p&gt;&#10;&lt;h2 id="_xlsx-file-format---more-information"&gt;_XLSX File Format - More information&lt;a class="anchor" href="#_xlsx-file-format---more-information" aria-label="Copy link to this section"&gt;&lt;/a&gt;&lt;/h2&gt;&#10;&lt;p&gt;The _XLSX files are no different than the XLSX files and use the Open XML standard adopted by Microsoft back in 2000. Before XLSX, &lt;a href="https://www.aspose.info/spreadsheet/xls/"&gt;XLS&lt;/a&gt; was the primary file format used for working with Excel spreadsheets to save documents in binary format. This new XML based file format came with advantages such as small file sizes, resistance to file corruption, and well-formatted images representation. This new XML based file format became part of Office 2007 and is carried out in the new versions of Microsoft as well.&lt;/p&gt;</description></item><item><title>CSV File Format</title><link>https://www.aspose.info/spreadsheet/csv/</link><pubDate>Tue, 10 Dec 2019 00:00:00 +0000</pubDate><guid>https://www.aspose.info/spreadsheet/csv/</guid><description>&lt;h2 id="what-is-a-csv-file"&gt;What is a CSV file?&lt;a class="anchor" href="#what-is-a-csv-file" aria-label="Copy link to this section"&gt;&lt;/a&gt;&lt;/h2&gt;&#10;&lt;p&gt;Files with .csv (Comma Separated Values) extension represent plain text files that contain records of data with comma separated values. Each line in a CSV file is a new record from the set of records contained in the file. Such files are generated when data transfer is intended from one storage system to another. Since all applications can recognize records separated by comma, import of such data files to database is done very conveniently. Almost all spreadsheet applications such as Microsoft Excel or OpenOffice Calc can import CSV without much effort. Data imported from such files is arranged in cells of a spreadsheet for representation to user.&lt;/p&gt;</description></item><item><title>DIF - Data Interchange File Format</title><link>https://www.aspose.info/spreadsheet/dif/</link><pubDate>Tue, 10 Dec 2019 00:00:00 +0000</pubDate><guid>https://www.aspose.info/spreadsheet/dif/</guid><description>&lt;h2 id="what-is-a-dif-file"&gt;What is a DIF file?&lt;a class="anchor" href="#what-is-a-dif-file" aria-label="Copy link to this section"&gt;&lt;/a&gt;&lt;/h2&gt;&#10;&lt;p&gt;DIF stands for Data Interchange Format that is used to import/export spreadsheets data between different applications.
