Online XLTX Editor

Edit XLTX file online from any device with a modern browser like Chrome and Firefox.

Powered By groupdocs.com and groupdocs.cloud.

Or open through direct link to the file

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 XLTX Editor App is exactly what you need!

With our XLTX 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.

FAQ

    ❓ How can I edit a XLTX file using XLTX Editor?

    First of all, you need to select and add this file for editing by two ways: drag and drop your file to the white area with the label ”Click or drop your file here” or click on this area and then select the desired file using file explorer. Once a file is added, the green progress bar will begin to grow, and when completed, the XLTX Editor will be opened with file content inside it.

    ⏱️ The Editor was opened after file uploading, but there is a “Please wait, while document is loading” message and no any document content. Will it appear and how long does it take?

    The document loading time depends on three factors: document size, the complexity of document content and aspects of the document format. For example, plain text files (TXT) are much easier to open and display than XLS spreadsheets, and it may be faster to open an eBook with a huge 1000 page novel inside rather than a complex 10-slide PPTX presentation with tons of animations, comments and images.

    📰 How can I edit the content of a document when it is opened in the Editor?

    In short: like in any other WYSIWYG-editor. There is a toolbar with three groups of tools: File, Format, and Insert. First group contains buttons for saving and downloading the document, second is responsible for formatting existing content, while third — for inserting the new entities inside content like images, tables, lists and so on. There also are two emerging groups of buttons on the toolbar — Table and List. They appear when you point at a table or a list respectively and contain tools for working with them like adding or removing table rows and columns, list indentation and so on.

    🛡 What about privacy, is it safe to use the XLTX Editor?

Finally, the uploaded file will be automatically deleted from our servers after 24 hours after uploading and this URL will become inactive.
