Bring your recipes with you

Paste a recipe from any calculator, a spreadsheet, or a forum post. You will see every line that was read and every line that was not, then open the result in the calculator. Soapee shut down in 2024 and took its users' saved recipes with it; nothing here is ever going to hold yours hostage.

Weights or percentages, grams or ounces. Lye, water, superfat and totals are recognised and kept out of the oil list.

Coming from a particular tool

SoapCalc. Use its print view or its recipe summary and paste the whole block. The oil list, the superfat and the water setting all come across. Its JSON export works too, though it does not carry mixed lye.

Soapee. The site shut down on 30 April 2024. If you kept a printout, a screenshot you can retype, or an old email, paste it here — the parser is deliberately forgiving because that is the shape those recipes are in now.

SoapmakingFriend. It has never had an export, so use the printed recipe or copy the ingredient list off the page.

SoapMaker 3. Its ingredient export is a spreadsheet; paste the name and quantity columns.

A spreadsheet or a notebook. Two columns, name and amount, is all this needs.

What it does not do yet

It reads oils, and the superfat, water and fragrance settings. It does not yet carry additives, colourants, fragrance blends or your notes across, and it will not invent an oil it does not recognise. Those lines are listed rather than guessed at.

Common questions

Which formats does it read?
All of them, approximately. There is no interchange format in soapmaking, so this does not target one vendor: it reads line by line, finds a name and a number, and works out whether your numbers are weights or percentages. A SoapCalc printout, a spreadsheet column, a forum post, a photo you retyped — all fine.
What happens to a line it cannot match?
It is shown with a dropdown so you can pick the oil yourself. It is never dropped quietly. If you open the recipe anyway, the button says how many oils it is taking and the percentages are renormalised over those.
My old calculator said a different amount of lye.
Then the two of you disagree about an oil, not about arithmetic — the saponification equation is the same everywhere. Ours shows the published range for each oil and names the document it came from — or says plainly that no document publishes one and the value is derived from the oil’s own composition — so open the oil page and see which number yours was using.
