XLSX Editor by Loam is a local workbook editor for .xlsx files. Open a workbook, move between sheets, edit cell values and formulas, and save your changes locally without an account. Work in a familiar spreadsheet workspace with a ribbon, formula bar, worksheet tabs, and files-and-sheets navigation. Switch between light and dark modes. Use the document tools to inspect and work with your workbook while keeping the sheet in view. Supported XLSX edits are written into the original workbook package. Imported formula results are retained until a cell edit. Supported formulas then recalculate locally; calculation coverage is partial. Advanced Excel features and unsupported edits may not behave as they do in Microsoft Excel. Keep a backup and check saved workbooks before relying on them. Workbook processing takes place on your device. The editor does not automatically upload opened workbook contents. Production desktop builds send limited usage analytics and error diagnostics as described in the privacy policy. If you choose to send a support request or feedback, your submission includes the message and reply email you provide; files are not attached automatically.
