Batching is the #1 reason users pay for PromptMix Pro. Here's exactly how it works.
1. Prepare your template
On the canvas, include placeholders inside double braces:
Write a friendly tweet promoting **{{product}}** that highlights **{{benefit}}**.
2. Create a CSV file
product,benefit
Acme Vacuum,Clean floors faster
Zest Protein Bar,High energy
...
Each row = one finished prompt.
3. Click Batch → Upload CSV
Free users will see the first 5 rows only (a preview). Pro removes the cap.
4. Export
- Export TXT – 1 prompt per line
- Export CSV – single "prompt" column for bulk import into Meta Ads, Google Sheets, etc.
Speed test: 100-row CSV → 100 prompts in < 3 seconds on a MacBook Air.
Common mistakes
| Error | Fix |
|---|---|
| Placeholder not replaced | Column name in CSV must match exactly ({{Product}} ≠ product) |
| Extra commas in output | Save CSV as UTF-8, no quotes needed |
Roadmap
We plan to add Live Preview (call your own GPT-4o key) so you can batch-generate and sanity-check results inside PromptMix. Stay tuned!
