If you need to edit documents in different formats using only the usual browser like Chrome, Firefox or Safari, without installing any editing software like Microsoft Office or OpenOffice, then XLSX Editor App is exactly what you need!
With our XLSX Editor App, which is absolutely free and doesn’t require registration, you can easily drag and drop the required file on upload form, edit its content right here in the browser, and then download the edited version in order to save it locally. Even more, you’re not forced to download the resultant file in the same format as you’ve uploaded it, — you’re able to choose any appropriate one! For example, you can upload a document in RTF format, edit it, and save as DOCX.
WYSIWYG-editor with its toolbar adapts to the specific format of an uploaded document, enabling those features and possibilities, which are actual for only this format and disabling those, which are not related. In particular, for Spreadsheet documents like XLSX, ODS, and CSV, there will be navigation between worksheets (tabs). For all document content the table editing mode will be enabled, but it is not possible to create new tables (because all content is the one single table) as well as the lists.
This online editor, because of its web-based nature, is absolutely portable and multi-platform — you only need a usual web-browser without any plugins, and no matter on which platform you’re using it: desktop PC or smartphone, Windows, Linux, or macOS, Android or iOS.
XLSX is well-known format for Microsoft Excel documents that was introduced by Microsoft with the release of Microsoft Office 2007. Based on structure organized according to the Open Packaging Conventions as outlined in Part 2 of the OOXML standard ECMA-376, the new format is a zip package that contains a number of XML files. The underlying structure and files can be examined by simply unzipping the .xlsx file.
You can also edit many other file formats. Please see the complete list below.
