Introduction

A procurement reviewer receives a vending equipment workbook with a total highlighted in green. The supplier option changed, but the cell still displays a plausible amount. Is that amount produced by the intended formula, copied from an earlier scenario or typed by hand? A result cell cannot answer that question by itself.

Microsoft documents a Show Formulas view that displays formulas in cells instead of their calculated results; its search guidance also describes using Ctrl+` (the grave accent key) to toggle the view. This is a review technique, not a proof that every formula is correct. It lets a buyer compare expressions, spot a replaced value and ask a precise question before an approval copy is issued.

This article applies that documented Excel behaviour to smart vending equipment procurement. It does not open or alter your workbook, test a WEIMI machine or certify a budget. The three products are a public-listing purchasing shortlist, not independently tested winners.

Quick Answer

Make a review copy that shows formulas, compare the expressions with the approved assumptions, then return to a clearly labelled results copy for the intended reader. In Excel, Microsoft describes selecting Formulas > Show Formulas, or pressing Ctrl+` to display formulas instead of results. Keep the original file and record which sheet, cells and revision were reviewed.

A formula-visible view can reveal a hard-coded value where a formula was expected, a reference to the wrong row, or a range that stops before a newly added item. It cannot prove that the source price, currency, tax treatment or machine configuration is correct.

Comparison Table

Review state What the reader sees Procurement question
Results view Calculated values such as a cabinet total or margin. Which formula or typed value produced this number?
Formula view Expressions such as SUM, links and cell references. Does the expression match the approved scope and period?
Values-only issue copy Fixed values prepared for a meeting or handover. Which formula-visible review and source revision support these values?
Unresolved exception Blank, error or unexpected expression. Who owns correction, and is the decision blocked or conditional?

The states are document roles, not Excel file types. Label them in filenames and meeting packs so a formula review is not mistaken for a commercial quote or a values-only approval record.

Who Should Buy This

This is for an operator or distributor whose budget uses formulas to combine cabinet price, options, freight, installation, payment hardware or launch allowances. It is useful when a second person must review a total without relying on the author’s memory of how the workbook was assembled.

A small purchase with a single written quote may need only a transparent arithmetic check. Do not add complex workbook controls simply because they sound rigorous. The review should match the decision risk and the number of moving inputs.

If a supplier provides only a PDF quote, formula visibility does not apply to the supplier document. Use the quote revision and your internal calculation as separate evidence; never imply that a formula view validates a supplier’s untested specification.

How We Evaluate Smart Vending Machines

Trace the calculation, then trace the equipment scope

First identify the decision cells: total investment, recurring service allowance, unit cost, forecast contribution and any approval threshold. Create a review copy and expose formulas. Compare the expression pattern across similar rows and periods. A copied result, an omitted row or a changed reference is a question to resolve, not automatic proof of an error.

Next compare the workbook assumptions with the proposed cabinet, product assortment, site, payment arrangement and support terms. Formula evidence cannot establish cooling performance, recognition accuracy, delivery or warranty. Those facts need supplier documentation or an agreed demonstration.

Our shortlist method

We read public WEIMI listings for an AI vision fridge, the WM22 touchscreen machine and a dual-cabinet snack-and-drink station. We use their published descriptions to identify which assumptions a formula may represent. No unit was purchased or independently tested, and no ranking, price or ROI result is claimed.

The Excel behaviour is based on Microsoft’s public Show and print formulas search result and its documented Show Formulas instructions. The procurement workflow is an editorial application; it is not a Microsoft or WEIMI integration requirement.

Key Buying Factors

1. List the cells that matter

Write down the exact cells or named outputs that drive the approval: hardware subtotal, configured options, freight, installation, payment setup and contingency. Formula review is most useful when the reviewer can state why each cell matters. A workbook-wide visual scan is not a substitute for a decision-cell list.

2. Compare patterns, not just one expression

Similar rows often should use similar formulas, but a legitimate exception may exist for a one-time charge. Compare the formula text, the referenced range and the period. If one row is a typed number among formulas, ask for its source and date. Do not “repair” it by guessing.

3. Preserve the original and the review copy

Showing formulas changes the display state of the worksheet. Save a separate review copy or document the toggle and return to the intended view before distribution. Do not overwrite the only working workbook while experimenting with review settings.

4. Separate formula evidence from source evidence

A formula can correctly add the wrong supplier line. A correct quote can be entered into the wrong cell. Keep the quote revision, currency, quantity and configuration beside the calculation review so the two evidence streams can be reconciled.

5. Record exceptions and approval conditions

If a formula is unclear, a source is missing or an option is unconfirmed, record the owner and next action. A neat total should not erase an unresolved question.

Best Smart Vending Machines

WEIMI Single-Door AI Vision Smart Fridge for Packaged Drinks

The public listing describes packaged drinks and compatible snacks, five shelf levels with five baskets, a 21.5-inch top screen or light box and optional 3–20°C cooling. It is a refrigerated retail cabinet, not a fresh-juice squeezing machine. A formula review can confirm that the selected configuration is priced in the model; it cannot confirm recognition performance or local payment support.

WEIMI WM22 Touchscreen Snack and Drink Machine

The WM22 page lists a 21.5-inch touchscreen, cooling and inventory functions, with optional spiral, conveyor, direct-push or hanging arrangements. The model should show only the mechanism actually quoted. Ask for a configuration-specific datasheet and product trial rather than treating every listed option as included.

WEIMI Two Cabinets, More Choice Station

The dual-cabinet listing shows a main cabinet and a secondary visible spiral-lane compartment. Confirm how the two sections map to payment, stock and delivery. A workbook total that combines only one cabinet’s line items is not a complete station budget.

Shortlist boundary: These are public-listing candidates for further review. Formula visibility does not make one the best choice. Select on confirmed site, product, payment and support fit.

Feature Comparison

Public feature Formula review question Evidence still required
AI vision fridge Does the model include the chosen cooling, display and onboarding scope? Configuration datasheet, package trial and written service terms.
WM22 options Does the formula charge only the selected dispensing mechanism? Sample test, lane arrangement and itemised option quote.
Dual cabinet Does the total include both selling sections and their interfaces? Reconciled two-section scope, mapping, payment and delivery confirmation.

The table connects listing language to review questions; it does not establish workbook import, API access or measured operating results.

Cost & ROI Analysis

Use a visible calculation chain

Show the cells that add equipment, options, freight, installation and project allowances. For recurring costs, show the period and units. Keep currency and tax assumptions visible. A formula view can expose the chain, but a reviewer still needs the source documents and a defined decision boundary.

Fictional review-time example, not machine ROI: Assume 35 minutes to inspect the approval cells, 30 minutes to compare formula patterns and 20 minutes to document exceptions: 85 minutes, or 1.42 hours. At a hypothetical loaded rate of US$46 per hour, the allowance is 1.42 × US$46 = US$65.32.

The duration and rate are assumptions for demonstrating workload. They are not a WEIMI price, customer outcome or measured saving.

Do not convert a formula review into a payback claim. Investment and cash forecasts need supported sales, operating and service assumptions. A transparent formula only makes the chosen arithmetic easier to inspect.

Best Choice by Scenario

A second reviewer is checking a capital request

Send the reviewer a formula-visible copy or guided screenshots of the decision cells, with the source quote revision. Ask them to compare ranges, options and units, then record exceptions before the meeting.

A management pack needs stable numbers

After review, issue a results copy or PDF labelled with the review date, source revisions and unresolved conditions. Keep the formula-visible review and working model available to the owner. Do not imply that a static result is a live forecast.

The workbook contains an unexpected hard-coded value

Pause the assumption and identify its owner. It may be a deliberate constant, a temporary placeholder or a lost formula. Replace it only after the source and intended logic are confirmed.

The site or assortment changes

Return to the working model, update the approved inputs and repeat the formula review. A prior results copy belongs to its original decision scope.

CONTROL CHECK 11

Applications

For a first cabinet, use formula review to connect the written quote to the selected option set and site allowances. For a distributor, separate supplier lines from internal service and contingency lines. For a fleet, sample the same decision cells across locations and record exceptions rather than assuming that one reviewed sheet represents every site.

FAQ

Does Show Formulas prove that the total is correct?

No. It exposes the expression or value for review. It does not validate source prices, ranges, currency, tax, configuration or business assumptions.

How do I toggle formula display in Excel?

Microsoft’s guidance describes Formulas > Show Formulas and the Ctrl+` shortcut using the grave accent key. Confirm the shortcut on the keyboard and Excel version in use.

Should I send the formula-visible workbook to management?

Choose the reader’s need. A review copy can help an analyst; a management pack may need a labelled results copy plus a retained review record. Do not hide the evidence or present a snapshot as live.

What if one row contains a value instead of a formula?

Record it as an exception and ask for its source and date. Do not infer that it is wrong or silently replace it.

Can formula review confirm a WEIMI machine’s energy use?

No. Ask for model-specific test conditions and a configuration-specific specification. Formula visibility only concerns the workbook calculation.

Can these machines import my Excel workbook?

This article establishes no import or integration feature for the three public listings. Ask WEIMI for supported interfaces if integration is part of your project.

Final Recommendation

Use a formula-visible review to make the approval calculation inspectable, then preserve a clearly labelled results copy for the reader who needs stable figures. Keep the original model and the source quote revision. Record exceptions instead of guessing at repairs.

Take the AI fridge forward when packaged-product, open-door retail is the intended format; the WM22 when its confirmed dispensing arrangement suits the assortment; or the dual-cabinet station when both sections have a documented role. In every case, treat public descriptions as a starting shortlist and confirm the project-specific specification.

A visible formula is evidence about the calculation expression. It is not evidence of a machine’s performance, an approved quote or a guaranteed return.
