Batch-Generate 100 AI Prompts in Seconds with PromptMix Pro

By PromptMix Team · Jul 1, 2025

Step-by-step guide on using CSV + placeholders to mass-produce tailored prompts.

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

Speed test: 100-row CSV → 100 prompts in < 3 seconds on a MacBook Air.

Common mistakes

ErrorFix
Placeholder not replacedColumn name in CSV must match exactly ({{Product}} ≠ product)
Extra commas in outputSave CSV as UTF-8, no quotes needed

Roadmap
