A few useful answers.
Can I try it without an account?
Yes. Try 10 requests a day without signing up. A free account includes 25 a day and recent formula history. The formula checker is free too. No card is needed to get started.
Does it work for Google Sheets?
Yes. Choose Excel or Google Sheets before you generate, explain, or fix a formula. Mention your Excel version if compatibility matters, and check the answer on sample data before relying on it.
What does verification actually check?
The formula checker executes supported functions on your sample data using the HyperFormula engine. This helps catch errors and compare actual results with your expectations. It is not native Excel or Sheets certification and cannot verify your business assumptions.
When should I choose a paid plan?
Start free and upgrade when you need more daily capacity. Pro includes your last 50 saved formulas and costs $4.99/month or ₹199/month. Usage safeguards apply. Compare current allowances and payment availability on the pricing page.
