Populate spreadsheets that require lookup tables of small primes for math models.

Generation is limited to 500 primes to keep the browser responsive.
The algorithm is simple trial division—sufficient for small lists but not huge primes.
Need larger primes? Pair this tool with the checker to validate numbers generated elsewhere.

Can I generate primes between custom ranges?: This version starts from 2 upward. Filter the output or adjust the code to support ranged generation.
Why is generation limited to 500?: Larger lists would slow the UI significantly. Adjust the max value in code if your device can handle it.
Does it include prime 2?: Yes. The sequence always begins with 2 and continues with successive primes.
