About Calculatorexe
Calculatorexe is a free collection of online calculators and tools. It started as grade and GPA calculators for students, teachers and parents in the US, UK, Canada, Australia and beyond, and now also includes a Shopify Product Extractor for online sellers. It exists because the grade questions people ask most — what do I need on my final? can I still reach a 3.5? am I on for a 2:1? — deserve exact, honest answers instead of rough guesses.
How we work
Every calculator on this site is built from the published formula for the job, shows that formula on the page, and works through real examples you can check by hand. The calculation code is covered by automated tests, including boundary cases (a final worth 0%, a target that needs over 100%) and the awkward rules that make grades tricky in real life: grade replacement, drop-lowest policies, credit weighting and UK borderline classifications.
We also say what a calculator cannot do. Results are planning estimates. Your school, college or university sets the official rules, and those always prevail — every tool on this site says so, because it is true.
The Shopify Product Extractor
Our newest tool helps online sellers move products into Shopify without re-typing catalogues by hand. It reads the public product data of compatible stores — Shopify, WooCommerce, Salesforce Commerce Cloud brands such as Khaadi and Sapphire, and custom stores — and produces a CSV in Shopify’s exact 96-column import format, with variants, sale prices, SKUs and images. Like the calculators, it is tested against real stores, and it is honest about its limits: when a store blocks automated access or hides its data, the tool says so per product instead of inventing data. Only extract products you have the right to sell — product text and photos belong to their source stores.
Privacy by design
All calculators run entirely in your browser. The numbers you type are never sent to a server, stored, or shared. The product extractor necessarily fetches the public links you submit — on demand, and storing nothing. You can read exactly what little data the site itself handles in our Privacy Policy.
