Stay free if you only need basic features. Upgrade if you need advanced features. Most solo builders can start free.
Copilot works inside Excel and is included with many Microsoft 365 plans, making it the default choice if you're already paying for Office. Ajelix's advantage is the persistent workspace and the ability to publish outputs as web apps and dashboards — features Copilot doesn't offer. However, Copilot has deeper integration with Excel's native features and benefits from Microsoft's enterprise security infrastructure.
It depends on your plan. The Free tier limits you to 2MB files, while the Max plan handles up to 500MB. For truly large datasets (millions of rows), you're better off with a dedicated data analysis tool like Julius or Python-based workflows. Ajelix is best suited for typical business spreadsheets in the thousands-to-hundreds-of-thousands row range.
Yes. Ajelix offers both Google Sheets and Excel add-ins that work in the browser. You can generate formulas, debug errors, and optimize spreadsheets directly inside Google Sheets without switching to the Ajelix web interface.
Ajelix claims GDPR compliance and states that data is encrypted at rest and in transit, with servers located in the EU. However, no independent security audit (such as SOC 2) has been publicly disclosed, and the platform does not publish a dedicated security page. If you're working with sensitive financial or personal data, verify their data handling policies meet your organization's compliance requirements before uploading.
