Turn the product idea below into a locally runnable MVP. ## Idea Spreadsheet Change Preview Before AI makes bulk changes to a business spreadsheet, users can see which rows will change, why they will change, and which formulas may be affected—then decide whether to apply them. ## Product concept When operations or finance teams ask AI to clean, classify, or rewrite business spreadsheets in bulk, the greatest risk is not that it cannot generate an answer. It is that a plausible-looking rule quietly corrupts hundreds of rows. A user describes an operation in natural language—such as standardizing customer categories, completing address formats, or recalculating a column—then selects the worksheet to process. The product runs the operation first in a sandbox copy, never touching the original sheet. The preview groups representative cells by change type and shows before-and-after values, the number of affected rows, and how related formulas would change downstream. Users can open any category, add instructions such as “exclude these customers” or “do not fill blank values,” and review the results again. Only after confirmation is the rule applied to the live spreadsheet, with a readable change summary, affected scope, and a one-click rollback point. If formulas, linked tables, or permission boundaries are uncertain, the system stops automatic execution and requires human confirmation. The first version handles only clearly structured spreadsheet changes; it does not make business-classification decisions for users or automatically overwrite source data. ## Why now (backed by facts) Teable 3.0 launched on July 14 as an “AI Spreadsheet for Business” and ranked 15th when viewed on July 25. As business spreadsheets begin to accept AI-driven bulk operations directly, validating and reversing changes becomes more urgent. ## Direction (model inference, not independently verified) Target user: Operations and finance staff who maintain customer, order, or budget tables. The need is most acute during month-end close, system migrations, or after bulk imports, when too many rows must change for cell-by-cell review. Their tables often contain formulas, linked fields, and historical exceptions. They want AI to move faster but will not risk overwriting production data directly. What they need is a quickly reviewable dry run, not another generation interface. Minimal entry point: Start as an external review layer for Teable rather than rebuilding a spreadsheet editor. Use the official API to read selected records and field metadata. Store a server-side copy of the original values, then run structured transformation rules. Group diffs by field, reason for change, and exception type, flagging formula, linked, and computed fields as high-risk first. Write changes back record by record only after confirmation, logging successes and failures. Rollback writes back the saved original values. Teable’s record history can supplement audits of individual cell changes. Initially, do not alter field structures, delete records, or handle cross-base migrations. The strongest case against: The primary risk is that the preview creates false confidence. Sampling can miss rare exceptions, and grouping can conceal flawed rules. If dependency detection is incomplete, formula issues may emerge only after changes are written back. Storing original values and writing them back also adds storage, permission, and concurrency-control costs. If a colleague edits the original sheet in the meantime, a rollback could overwrite legitimate updates. Sensitive business data may also be unable to leave the organization for an external model. Field-level permissions, redaction, and conflict detection are essential; without them, users may prefer copying a worksheet and comparing it manually. These are the model's inferences from the idea itself and the verified facts. Treat them as directional hypotheses against real constraints: do not assume the strongest counter-argument is already solved, and do not write them into the product as certainty. ## Punching above weight (model inference) Build early momentum around real examples of AI bulk-edit failures in spreadsheets. Use anonymized sample tables to show before-and-after diff reports, and publish reusable templates for customer classification, address standardization, and blank-value handling. Find frequent cleanup tasks in Teable, Airtable, and spreadsheet-automation communities. Offer one free preview and make the review report easy to share; reports forwarded within a team can bring in new users. ## Competitors & gaps (model inference) - Gemini in Google Sheets: Gemini can already use natural language to fill ranges, find and replace, delete rows, and adjust formatting. It shows an action-preview card before applying changes and offers undo afterward. That covers the basic describe-then-apply flow. Its public help documentation does not say that it samples changed cells by change type or summarizes the number of affected rows in each category. Complex requests can combine several actions, leaving users to judge whether the full set may cause unintended changes. Undo is also affected by subsequent edits, making it unsuitable as a persistent rollback point. The opportunity is not to edit spreadsheets better, but to make diff review a separate workflow—highlighting exceptions, formula impact, and saved reverse changes. - Airtable Field Agents: Airtable Field Agents can generate or analyze data at the cell level. Users can also run them in bulk on the current view, stale cells, or cells with errors. They are suited to ongoing completion, classification, and generation of field content. Configuration is centered on field agents and their prompts, and the scope of bulk runs is relatively clear. Public documentation does not indicate that it generates a pre-run, cross-field diff of changed cells or shows the downstream effects on linked and computed fields. If users spot a flawed classification rule, they will often need to revise the prompt and run it again. The opportunity is to turn a batch run into a reviewable change package: users can exclude specific records, recalculate under the same rule, and then approve it. ## How it makes money (model inference) Charge a monthly fee per workspace, including a set number of previews and executions. Sell additional processing batches beyond that allowance, rather than charging per cell, so opaque costs do not lead users to skip verification. ## Source context Theme: Teable 3.0 business AI spreadsheet Trigger Product Hunt launch: Teable 3.0 — AI Spreadsheet for Business This records only that the launch appeared in Product Hunt's public feed and when it was observed. The feed provides no vote count; do not describe feed order as popularity or market demand. ## Sources - Teable 3.0 (https://www.producthunt.com/products/teable-4) - https://help.teable.ai/en/api-reference/record/get-table-records-history - Collaborate with Gemini in Google Sheets (https://support.google.com/docs/answer/14356410?hl=en) - Using Airtable AI in fields (https://support.airtable.com/docs/using-airtable-ai-in-fields) ## Deliverables - Before you start, distill 3–5 verifiable acceptance criteria from the concept and minimal entry point above, list them, and walk through them one by one on delivery. - Ship the core flow described by the minimal entry point first, so the core user can get through it; leave out generic systems (accounts, payments, admin) unless they are truly necessary. - Do not show unverified market numbers in the UI or API. - Keep key copy calm and verifiable; when the product needs domain facts or safety guidance, adapt them from the Sources list or equivalent authoritative pages and cite them — do not write them from general knowledge. - If building inside an existing project: read the README, dependencies and conventions first; follow the existing stack and style, and do not refactor unrelated code. - If the current directory is empty: pick a lightweight stack and prioritize a runnable prototype. - When done, explain what changed, how to run it, and how to verify it. - Ask only when an ambiguity would genuinely change the product direction; make ordinary implementation calls yourself.
