Supported formats of spreadsheets
A spreadsheet is a table of data organized in rows and columns. It is most frequently used to store financial information because of its ability to re-calculate the entire sheet automatically after a change to a single cell is made. The Spreadsheet Editor allows you to open, view and edit the most popular spreadsheet file formats.
While uploading or opening the file for editing, it will be converted to the Office Open XML (XLSX) format. It's done to speed up the file processing and increase the interoperability.
The following table contains the formats which can be opened for viewing and/or editing.
