Below is a practical, copy-pasteable guide that gives ready-to-use prompt templates and examples to generate PrestaShop-ready product, category, and CMS content with an LLM (ChatGPT or similar). It focuses on structure, SEO, data fields, formats, and best practices so you can generate consistent, importable content.
Short principles
- Be explicit about output format (JSON or CSV-ready). This makes parsing and import easier.
- Give required fields, character limits, allowed HTML, and exact keys that match your import tool/CSV columns.
- Provide examples and constraints (word counts, tone, slug rules).
- Prefer low temperature (0–0.3) for reproducible output.
- Validate output for uniqueness, SEO length, and HTML safety before import.
General PrestaShop-aware rules to include in prompts
- link_rewrite (slug): lowercase, letters/numbers/hyphens only, max 128 chars.
- meta_title: ≤ 70 characters (aim 40–60).
- meta_description: ≤ 160 characters.
- description_short: short HTML snippet (use
,
, - , , ,
).
- description: full HTML product description (can include headings).
- Tags: comma-separated, no duplicates.
- Image captions/alt: describe image briefly, ≤ 120 chars.
- Prices: include currency; do not include taxes if your store expects net price (specify).
- Attributes/combinations: list attribute group name and option.
- Avoid brand claims or regulatory statements if unsure.
Recommended LLM settings
- Temperature: 0–0.3
- Max tokens: 300–800 depending on volume
- Stop sequences: none necessary if returning strict JSON
- System message (optional): “You are a helpful content generation assistant for PrestaShop. Output only valid JSON matching the requested schema. Validate SEO lengths and slug rules.”
1) Product prompt template (JSON output)
Prompt skeleton (paste & fill the "Product data" section):

",
"active":true
}
Multi-language generation
- Request a top-level JSON with keys per language, e.g. "en", "fr", "de", each containing the same schema.
- Specify which fields should remain untranslated (brand names, SKU, technical specs).
Example instruction: “Translate name and descriptions into French and German; keep SKUs and measurements unchanged.”
Bulk generation tips
- Provide a CSV with base columns: title, brand, short_description, features, price, images, categories, attributes.
- Use the LLM to expand each row into the JSON schema or create the SEO fields and descriptions.
- For large batches, generate unique meta_title/meta_description templates using variables (brand + product short selling point).
Validation checklist before import
- link_rewrite: no uppercase, no special chars, unique per category
- meta lengths: meta_title ≤ 70, meta_description ≤ 160
- No disallowed HTML tags
- Images reachable and correct format (prefer .jpg/.png)
- No inline JS, no external references in descriptions
- Attribute names match PrestaShop attribute groups
- Prices use correct currency and decimals
Quick sample prompts you can paste
- Single product: paste the product prompt skeleton above and fill product-specific data.
- Multiple languages: add “Return the same JSON for: en, fr” and include translations requirement.
- Strict JSON only: Prepend “Return only a single JSON object and nothing else.”
Final tips
- Start with small batches and manual review.
- Use low temperature for consistent slugs and meta fields.
- If you need direct CSV/Excel mapping for PrestaShop Manager or native PrestaShop import columns, tell me the exact column names and I’ll produce a prompt that outputs a CSV-friendly row.
If you want, paste one product (title + features + images + price + sizes/colors) and I’ll generate the exact JSON/CSV row ready for import.
