33 resources to explore · Illustrative, not tool-tested
Clean a messy inventory list
A consistent, traceable stock list plus a separate queue of questions to resolve.
Make a product listing and clean import CSV
A complete fictional listing, a fact-to-claim map and a two-variant CSV that matches a declared generic schema.
Preview a batch rename without touching your files
A six-row rename preview with one ready proposal, four blocked rows and one no-op. No actual user file operations.
Turn a spreadsheet rule into a formula you can check
A proposed single-cell Google Sheets formula, a pasteable eight-case synthetic grid, an independent answer key and a procedure for checking actual results and recalculation. The downloadable pack is documentation-reviewed; Google Sheets execution and the AI workflow remain unperformed.
Split shared expenses using rules everyone agreed
A six-expense allocation CSV and three-person balance CSV you can trace to the supplied rules. The example handles one excluded payer, one individual purchase and a leftover penny; it does not move money.
Turn a table image into a checked CSV
A six-row CSV with every equipment ID and unit preserved, one uncertain quantity left blank and a review note explaining what needs a clearer source.
Match two lists by ID without losing rows
A nine-row match-and-exception CSV: three confirmed pairs, one equipment-only row, one request-only row and four held source rows for one duplicated key. All twelve input rows remain traceable exactly once.
Scale ingredient quantities while keeping exact fractions
A source-linked static ingredient-scaling worksheet with exact numerators/denominators, readable mixed fractions and unresolved fractional-item decisions. The fictional example scales four portions to six; it does not validate a cooking method.
Estimate paint quantities from your supplied wall measurements
A source-linked area worksheet and whole-pack shopping list, with explicit supplied assumptions, budget checks and a reusable blank worksheet. It is an estimate to review before buying, not wall preparation or application advice.
Check a small craft order’s costs before quoting
A reusable blank cost worksheet and exact worked breakdown, with a checked whole-penny price boundary under the supplied fee and residual rule. Missing real costs remain unknown, and choosing or sending an actual quote stays with the owner.
Keep track of things you lent or borrowed
Reconcile item-level handoffs and partial returns without inventing due dates or sending reminders. The worked result is a written example for practice; the AI steps have not been tested.
Make a where-is-it index for stored belongings
Build a searchable text location index with aliases and explicit unknown locations. The worked result is a written example for practice; the AI steps have not been tested.
Combine recipe ingredients into one shopping list
Sum compatible ingredient quantities across supplied recipes, subtract usable stock and keep incompatible units separate. The worked result is a written example for practice; the AI steps have not been tested.
Make a restock list from counts and your own thresholds
Calculate top-up quantities using owner-set trigger and target counts, preserving uncertain stock and incompatible item types. The worked result is a written example for practice; the AI steps have not been tested.
Sort support requests using explicit routing rules
A ticket-to-queue ledger with clear evidence and unrouteable requests held
Hand over guest-service requests without losing their status
A token-based relay log distinguishing received, in progress, delivered and unresolved requests
Reconcile event sign-ups with cancellations and waitlist places
A status-aware registration total and unresolved record queue without creating admissions
Add useful search tags to a small asset library
A controlled tag list and asset-by-asset assignments using only supplied descriptions
Calculate an average when the groups are different sizes
A source-linked weighted average with its component totals, denominator and explicit missing-data limits. This is an authored practice example; no consumer AI run has been recorded.
Check several partial deliveries against one order
A line-by-line received, outstanding and over-delivered ledger, with duplicate delivery references held before totals. This is an authored practice example; no consumer AI run has been recorded.
Make a CSV that keeps commas, line breaks and leading zeroes intact
A correctly quoted small CSV and an import-review checklist that preserves exact text fields rather than silently converting them. This is an authored practice example; no consumer AI run has been recorded.
Move a short melody into a different supplied note range
A note-by-note transposed pitch list, preserved rhythm and interval check, plus an explicit hold if the requested range cannot contain it. This is a written practice result, not a recorded AI run.
Work out what goes in each workshop kit
A per-kit bill of materials, batch picking totals and shortages, separating shared tools from consumables. This is a written practice result, not a recorded AI run.
Check whether clean linen lasts until the next return batch
A dated clean/issued/dirty/in-laundry balance ledger, earliest shortfall and conditional replenishment question. This is a written practice result, not a recorded AI run.
Explain what every column in a small dataset means
A data dictionary with row grain, units, allowed values, missing markers and questions that stop unsafe interpretation. This is an authored practice example; no consumer AI run or real participant trial has been recorded.
Count records by two categories without losing the totals
A complete two-way count table with row, column and grand totals, including unknown categories. This is an authored practice example; no consumer AI run or real participant trial has been recorded.
Move categories to a new scheme without hiding lost detail
A source-to-target category crosswalk with one-to-one, many-to-one and unresolved split mappings, plus an information-loss report. This is an authored practice example; no consumer AI run or real participant trial has been recorded.
Turn repeated month columns into a tidy list
A long-form table that preserves each original cell, explicit blanks and row keys, with a reversible mapping check. This is an authored practice example; no consumer AI run or real participant trial has been recorded.
Find where a small process spent time waiting
A timestamp-based elapsed-time breakdown separating active work, waiting and unknown intervals, without inferring blame or causes. This is an authored practice example; no consumer AI run or real participant trial has been recorded.
Summarize a survey without using the wrong denominator
A descriptive result table that distinguishes respondents, answered questions and multiple selections, with skipped questions visible. This is an authored practice example; no consumer AI run or real participant trial has been recorded.
Make a subject index that leads to useful passages
An alphabetized subject index with subentries, alias redirects, section locators and an inclusion/exclusion ledger. This is an authored practice example; no consumer AI run or real participant trial has been recorded.
Count ranked choices for a casual group decision
A round-by-round tally of a supplied ranked-choice poll, showing each ballot’s current choice, transfers, exhausted ballots and a rule-bound result or unresolved tie. This is an authored practice example; no consumer AI run or real participant trial has been recorded.
Keep an estimate honest when the inputs are ranges
A lower-and-upper estimate from supplied bounds, with definite-fit, definite-no-fit and unresolved-fit conclusions under an explicit simple model. This is an authored practice example; no consumer AI run or real participant trial has been recorded.
