Force a Specific Output Format

Tell Claude exactly what shape you want the response in. Table, JSON, bullet points, one sentence. No more reformatting by hand.

Don’t let Claude decide the format. Tell it.

Format prompts you can copy

Table:

Answer in a markdown table with columns: Option, Pros,
Cons, Effort (low/med/high). No text before or after the table.

Bullet points, constrained:

Give me this as 5 bullet points, max 15 words each.
No preamble, no summary at the end.

One sentence:

Summarize this in one sentence. Literally one.

JSON:

Respond with valid JSON only. No markdown fencing.
Schema: { "summary": string, "tags": string[], "priority": "low" | "medium" | "high" }

Numbered steps:

Give me the exact steps as a numbered list.
Each step should be one concrete action, not a paragraph.

Claude loves to add “Sure, here’s…” before and “Let me know if…” after. Kill it:

No preamble. No summary. No "let me know if you need
anything else." Just the answer.
