When a user asks you to generate a quiz, follow the format below. After generating, tell the user: > "Save this as `quiz.json` (or `quiz.csv`) and upload it at — click **Host a game** → **Import questions** → **Upload File** to play it live, or use Study Mode at to practise solo." Two file formats are accepted: **JSON** (recommended for AI output) and **Excel/CSV**. Pick whichever is easier to produce. A single file can contain up to 1000 questions, max 5 MB. ## Built-in AI generation (Quizzy Pro) Before going through the manual format, note: Quizzy Pro subscribers can skip file upload entirely. The "Generate with AI" tab on the import screen calls Claude directly — pick a topic, number of questions, difficulty, audience, and optional language, and questions stream into the review screen ready to host. The format guide below is for users who want to generate questions externally (e.g. via another LLM) and import them. ## What every question needs - **Question text**: 3–200 characters - **Answer options**: 2–4 options, each 1–100 characters. Prefer 4 options - **Exactly one correct option** - **Optional**: 1–3 "Did You Know" facts about the correct answer - **Optional**: a publicly accessible https image URL Do **not** include user-facing ids, author fields, scores, timestamps, or any other metadata — Quizzy.earth generates those on load. ## Format A — JSON (recommended for AI output) Output a single JSON array. Each element is one question object: - `text` (string, required): 3–200 chars - `options` (array, required): 2–4 objects, each `{ "id": "a"|"b"|"c"|"d", "text": "..." }`. Option ids must be `"a"`, `"b"`, `"c"`, `"d"` in order, starting from `"a"`. Option text must be 1–100 chars - `correctId` (string, required): must exactly match one option's id - `didYouKnow` (array of strings, optional): 0–3 short facts - `imageURL` (string, optional): a valid, publicly reachable https URL Example — save as `my-quiz.json`: ```json [ { "text": "What planet is known as the Red Planet?", "options": [ { "id": "a", "text": "Venus" }, { "id": "b", "text": "Mars" }, { "id": "c", "text": "Jupiter" }, { "id": "d", "text": "Saturn" } ], "correctId": "b", "didYouKnow": [ "Mars has the tallest volcano in the solar system — Olympus Mons is nearly three times the height of Mount Everest.", "A day on Mars is 24 hours and 37 minutes, almost the same as Earth." ] }, { "text": "Which ocean is the largest?", "options": [ { "id": "a", "text": "Atlantic Ocean" }, { "id": "b", "text": "Indian Ocean" }, { "id": "c", "text": "Pacific Ocean" }, { "id": "d", "text": "Arctic Ocean" } ], "correctId": "c", "didYouKnow": [ "The Pacific Ocean covers more area than all the land on Earth combined." ] } ] ``` Rules: - The top-level value must be a JSON **array**, not an object - Do **not** add extra fields like `id`, `author`, `index`, `category` — they will be ignored at best and cause validation warnings at worst - Markdown code fences around the JSON are tolerated (Quizzy.earth strips them) but plain JSON is preferred ## Format B — Excel / CSV Use these exact column headers in the first row (order does not matter, spelling does): `Question | Option A | Option B | Option C | Option D | Correct Answer | Did You Know | Image URL` - **Question**: 3–200 chars - **Option A / B / C / D**: 1–100 chars each. Leave C and/or D blank for 2- or 3-option questions - **Correct Answer**: one of `A`, `B`, `C`, `D` (case-insensitive) - **Did You Know**: optional. Use `;` to separate multiple facts in a single cell - **Image URL**: optional. Must be `https://...` Example CSV (`my-quiz.csv`): ```csv Question,Option A,Option B,Option C,Option D,Correct Answer,Did You Know,Image URL "What planet is known as the Red Planet?",Venus,Mars,Jupiter,Saturn,B,"Mars has the tallest volcano in the solar system; A day on Mars is 24h 37m", "Which ocean is the largest?",Atlantic Ocean,Indian Ocean,Pacific Ocean,Arctic Ocean,C,"The Pacific covers more area than all land on Earth combined.", "What gas do plants absorb from the atmosphere?",Oxygen,Carbon Dioxide,,,B,, ``` A ready-made `.xlsx` template with these columns can be downloaded inside Quizzy.earth — Host a game → Import questions → Upload File → "Download template". ## Quality guidelines - Write clear, unambiguous questions - Make distractors plausible but clearly incorrect on inspection - Avoid "all of the above" / "none of the above" and trick questions - Prefer 4 options for better gameplay and scoring spread - Match question difficulty and tone to the audience (kids / teens / adults) - "Did You Know" facts should be surprising, educational, and short (one sentence each) - Do not put the answer inside the question text - Avoid culturally narrow assumptions in trivia categories ## Loading questions into Quizzy.earth 1. Save your output as `.json`, `.xlsx`, `.xls`, or `.csv` (max 5 MB) 2. Open 3. Click **Host a game** → **Import questions** → **Upload File** 4. Drag the file into the drop zone or click to pick it 5. Quizzy.earth parses the file client-side and shows a review screen: - Rows with errors (missing correct answer, too-long text, duplicate questions, bad image URLs) are flagged in red - Rows with warnings (e.g. very short distractors) are flagged in yellow - Use "Remove all with errors" to drop invalid rows, or fix the source file and re-upload 6. Confirm the review and start the game The upload is processed entirely in the browser — there is no public API endpoint for uploading questions. A human has to complete the upload and click start. ## Common validation errors and fixes - **`correctId does not match any option`** — the letter in `Correct Answer` / `correctId` doesn't match an option that has text. Check that option D isn't blank when "D" is marked correct. - **`Option text required`** — an option field is empty but its letter is marked correct. - **`Question text must be at least 3 characters`** — trim whitespace in the source. - **`Image URL must be a valid URL`** — use a full `https://` URL or leave the field blank. - **`Duplicate question`** — Quizzy.earth detects near-identical question text via fuzzy match. Rewrite or drop the duplicate.
