Map form fields to fictional data before filling

Use fictional form fields and data to identify gaps, format ambiguities and competing mappings.

適用情境 / When to use

Dave Swift describes a Claude Code PDF workflow in an article with sponsorship and referral links. This exercise uses fictional fields, not the article’s tax forms or identifiers.

步驟 / Steps

1. Open an ordinary text chat at gemini.google.com with an eligible account. Prepare shareable or fictional plain text using the prompt parameters; transcribe it yourself and mark ambiguities. Do not upload source files or connect accounts.
2. Paste the text and prompt; request only a draft, comparison or plan, not tool execution.
3. Check every output against supplied sources, references and unknowns. A human decides next steps; no automatic publishing, payment or deployment.

提示詞 / Prompt

Using [fictional ordinary form fields: IDs, labels, types, formats and required conditions] and [fictional key-value data], draft a field map. List each original field, candidate data, evidence, format questions and gaps. Similar names need not identify the same field. Ask about ambiguous dates, addresses or units instead of guessing or truncating. Supply no real identity numbers, tax IDs, accounts or signatures. Work with text only: do not read or fill PDFs, execute code, sign or submit. Text checks do not verify layout or form validity.

留意事項 / Cautions

• Text mapping does not establish fillable PDF fields, correct layout or document validity.
• Checked 2026-10-30: official Gemini web lists Hong Kong, Macau, Taiwan, Traditional/Simplified Chinese and English; account and age eligibility apply. Limited use is available without a paid AI plan and varies by account and workload. Taiwan’s public subscription page lists Free at NT$0/month; no paid plan is required for this exercise. HK/Macau paid prices and local taxes, offers and final quotes are unverified. Output quality in all three languages is untested. Web eligibility does not establish App/API eligibility; neither is needed here. Original-tool regional features, devices and paid eligibility are unconfirmed; do not bypass restrictions. Android’s official region list also includes HK/Macau/Taiwan. The iOS and AI Studio/Gemini API lists include Taiwan, not Hong Kong or Macau; feature and device restrictions still apply.
