Excel to ODS Conversion

8 Mar 202212 minutes to read

The Open Document Format for Office Applications (ODF) is also known as OpenDocument. It is an XML-based file format for spreadsheets, charts, presentations, and word processing documents. It was developed with the aim of providing an open and XML-based file format specification for office applications. OpenOffice uses ODF format as its default document format. The OpenDocument Spreadsheet (ODS) is the file format for Excel documents. XlsIO supports conversion of XLS/XLSX documents to ODS.

Saving ODS in different platforms

The following code snippet illustrates the creation of an Excel file and exporting it to ODS format.

using (ExcelEngine excelEngine = new ExcelEngine())
