How to use GridCraft online

Open a supported spreadsheet or start a workbook in the editor.
Work on the data
Edit cells and formulas, check the active sheet and review any calculated results.
Save the workbook
Download the workbook or export a supported format for its next use.
Before you start
Formula and file compatibility can differ from other spreadsheet programs. Agent writes are limited to supported ranges and checked against workbook and sheet identity. Review formulas and keep a backup of important workbooks.
Free manual editing, optional AI
Use GridCraft manually without an account. Sign in to use shared EasyRunCraft credits for supported AI tasks. AI requests send the context or attachments needed for the task.
One account and one balance cover all thirteen tools. AI credit usage depends on the task, content and model. Manual editing, saving and exporting do not use credits. See how credits work and examples, compare plans and credit packs, or read our Privacy Policy.
GridCraft questions
Can GridCraft open an XLSX file online?
Yes. Open a supported XLSX file in the browser workbench, review its sheets and save a copy after editing. Complex features may not import identically.
Can I undo an Agent cell edit?
Supported Agent writes use native spreadsheet commands and undo. If the workbook changes after inspection, its identity and revision guards can reject a stale edit.
