Overview

Edit XLSX Files Locally in Your Browser (No Uploads)

ExcelCraft is a free, local-first online Excel editor designed to open and edit XLSX files directly in your web browser.

Its main purpose is to let you work with Excel spreadsheets without uploading them to external servers.

This makes it useful when you need to edit sensitive or private files while staying in a browser-based workflow.

To use it, you simply open the app and load an XLSX file to start viewing and editing.

Because the workflow is local-first, it helps reduce the friction of moving files between devices, apps, or cloud services.

It also supports quick edits when you don’t have desktop Excel available or don’t want to install software.

The feature is especially helpful for working on spreadsheets on shared or restricted machines where uploading files is not allowed.

It fits common tasks like reviewing data, making small corrections, and updating spreadsheet content on the go.

Overall, ExcelCraft provides a convenient way to handle XLSX editing in-browser while keeping your files local.
