Start with GridCraft online
This is an independently hosted official Web release. No account or desktop installation is required to open it. Use a current desktop browser and wait for the first application download.
- Create a small workbook or open a duplicate XLSX.
- Enter known values and a simple formula.
- Change an input and verify recalculation.
- Download a separate XLSX and inspect the saved cells and formulas.
Know the browser and file limits
Opening an XLSX does not establish support for all Excel features. Macros, external links, add-ins, complex formulas and PivotTables require separate checks.
Keep your files and a separate backup
Editing runs on your device. This site provides application files, not a file-upload processing server. Browser storage and temporary memory can be lost. Download your work before closing, restarting or clearing site data.
The editor entrance records page visits in Google Analytics. File contents and editing actions inside the workspace are not collected. Advertising is outside the workspace; the Privacy choices control lets you turn analytics and advertising off independently.
Check the output you actually need
Check the formula text as well as its result and reopen the downloaded workbook. Our basic browser verification does not certify workbook compatibility.
Our release verification records startup and bounded sample checks separately. It is not a compatibility certification. Keep your current production workflow until your own saved output passes its receiving application’s checks.
Continue with a small working copy
Open GridCraft online above, keep the original separate and download a result you can inspect. If the browser cannot start, return to the official release for a desktop package.
