Excel Master

ExcelMaster.ai is a Windows desktop Excel add-in from MatrixTech LLC. Its current website describes an agent that reads workbook structure, writes formulas or VBA, executes changes and checks results. Higher plans also list Python automation and multi-step workflows. This is a tool for changing spreadsheets, so reviewing proposed operations and keeping independent backups matter more than treating its chat as harmless text advice.

The site specifies desktop Excel on Windows, with support for workbook and macro-enabled formats. It describes code previews, checkpoints and rollback, but these safeguards and the advertised accuracy comparisons were not independently tested. A public trial button opened an empty email or Google sign-in screen. No email was submitted, Google authorization granted, installer downloaded, workbook uploaded or code executed.

The observed monthly grid shows Starter at $9.99 with six hundred agent credits, Pro at $29.99 with eighteen hundred, and Premium at $79.99 with forty-eight hundred. Credits follow actual AI usage rather than a fixed number of completed tasks, and unused subscription credits do not roll over. The site also offers separate credit packs and a three-day trial on selected plans. An annual billing toggle exists, but those prices were not checked. Currency code, taxes, renewal details and final checkout totals were not independently confirmed.

The older terms and privacy policy describe transferring worksheet metadata to third-party AI providers. The current FAQ says relevant cell contents can be sent while the full file stays local. These descriptions should not be read as a promise that no spreadsheet data leaves the computer. Exact retention periods and the providers' current contracts were not established. Confirm those boundaries before using customer, financial or other sensitive workbooks. Free download does not establish unlimited free agent use.
