GridCraft: spreadsheets, formulas and XLSX files

GridCraft formulas, tables and charts

The official page describes a spreadsheet interface with a formula bar, worksheet tabs, calculation functions, dynamic arrays, charts and PivotTables. Treat these as documented capabilities to inspect in the release you choose. We have not measured calculation correctness or workbook performance.

Use a small copy of a real workbook with known expected totals. Include only the features that matter to your job. An empty sheet cannot tell you whether a formula, validation rule or chart survives the handoff.

Check XLSX values and formulas separately

The maintainer describes XLSX reading and writing. That does not verify every Excel workbook or automation feature. Compare formula text and results, then recalculate after changing an input. Inspect date and number formatting as well as the displayed totals.

If your workbook depends on macros, external links, add-ins or a particular function, verify that requirement explicitly against the release documentation and a trial. Do not assume that opening an XLSX establishes support for everything stored inside it.

Inspect the analysis and presentation layers

Check tables, validation, conditional formatting, charts and PivotTable grouping against a reference. Change the underlying data and confirm that the dependent view updates in the way you need. A correct-looking chart can still be based on a stale range.

Save a separate XLSX and reopen it in the recipient’s spreadsheet editor. Inspect both editable structure and any print or PDF reading copy. Keep the original workbook until the calculations and handoff meet your requirements.

A first GridCraft workbook check

Choose a workbook small enough to inspect cell by cell. Record the application version with your expected totals.

1. Keep the original XLSX and note a few known formula results.
2. Open a duplicate and change one meaningful input.
3. Check recalculation, formatting and the affected chart or PivotTable.
4. Save a new XLSX, reopen it in the receiving editor and compare the results.

GridCraft versions: official downloads and this site

On 18 October 2026, the official GridCraft product page linked to 0.5.0 packages; the GitHub latest-release page resolved to 0.8.0. Use the version attached to the file you actually download and read that release’s notes.

Our hosted GridCraft browser editor uses 0.8.0. The application files were updated in this release. Startup, a small sample and your own file compatibility remain separate checks. Download your work before closing.

Choose a small task before changing your workflow

For GridCraft, start with the representative check above and keep both the original and the saved result. Choose the official download for your operating system and processor, then inspect that exact version. A release number, screenshot or feature list cannot establish that your own file is ready to deliver.
