Best practices for getting cleaner results from PromptCell.
The strongest PromptCell prompts describe the job, the desired output, and any important rule you want preserved. Start with the business task, then add constraints only when you need them.
Bestfor specific jobs like clean, summarize, extract, and match
Useextra ranges when the answer needs grounding from another sheet
Startwith ASK and only force GEM or CLD if needed
Best practices
Pass the range that matters
PromptCell only sees the values you pass into the formula. Include other sheets or ranges when the job depends on them.
Pick the output shape first
Use ASK for one answer, ASKR when the output must keep the same shape, ASKT for a new table, and ASKX for lookup-style matches.
Keep instructions concrete
Short prompts with a clear desired result usually beat long multi-paragraph instructions.
