Five tools for stores, warehouses and inventory teams whose records live in Excel or CSV: find dead stock in years of movement history, reconcile two stock reports, run a physical count against book stock, check a 3PL invoice against your rates and records, and turn an existing workbook into a clear dashboard. Files are read in your browser, and every result points back to the rows behind it.
Free to use, no account or payment details needed. Your files are read in your browser and are not uploaded. How it works
Each one reads your Excel or CSV files inside your browser and gives you an Excel report you can check line by line. The screens below show invented sample data. All five are beta versions, tested on synthetic data.
Find stock with no qualifying movement for 1, 2, 3 or 5 years from years of movement history, with the source rows behind every result.
Compare two stock reports line by line — system against warehouse, or two dates. Shows matched lines, quantity differences, lines missing from either report, duplicate keys and ambiguous matches, with the reason for each.
Run a stock count against book stock: count sheet to print or fill in, counts imported or typed on screen, variance by line, recounts and reviewer comments.
Choose the spreadsheet you already keep, in your own layout (up to four files). The designer reads it, says what it found and what is missing, asks only what it cannot tell, and makes a clear workbook from your actual data: a WarehouseCalc attendance register or stock list, a new register from an employee list, or a redesigned copy with a dashboard.
Check a 3PL invoice against your contracted rates and your own order, shipment and receipt records. Every flagged line shows the billed and expected amount, the evidence used and what to do next; a line that is not flagged was not contradicted by the checks that could run.
Keep your stock records in Excel: stock in, stock out and balances, every row checked, no macros. These are not beta tools and need no account: Simple is free for everyone, Custom and Advanced are paid once; their prices are on the workbooks page.

Open any tool and start. There is no sign-up, no approval and no payment. The tools are still in beta: results have been checked on synthetic data, so compare them with what you know and tell us what is wrong or missing on the contact page.
The tools read your Excel and CSV files inside your own browser tab. They are not uploaded to WarehouseCalc or anyone else, stored in a database, or sent to an AI service. In our tests the only requests the tools made were for their own program files and sample files. Reports are created in your browser and saved straight to your device. Like any website, our hosting and security providers see ordinary request information such as your IP address. No account is needed, so we keep nothing about you for the tools. Read the privacy notice.
Yes. The five tools are free to use and need no account, sign-up or payment details. The Excel inventory workbooks below are separate: Simple is free, Custom and Advanced are paid once.
No. Open a tool and use it. Accounts from the earlier controlled beta still work but are not needed.
Excel .xlsx and CSV (.csv or .txt; comma, semicolon, tab or bar separated). The Workbook Designer also reads .xlsm, but its copy has no macros. Old .xls, .xlsm, .ods, password-protected and PDF files are not read: save them as .xlsx or CSV first (for a 3PL invoice, ask the provider for the invoice detail as Excel or CSV). Up to 50 MB and 300,000 rows per file.
Dead Stock Analyzer: item code, date, movement type (or quantity in and out) and quantity — or one row per item code with a column per month of consumption and the current stock. Stock reconciliation: two stock reports with item code and quantity; location, batch, lot and unit cost help. Stock count: a book stock list (item code and quantity) and the counts, from a file or typed on screen. Workbook Designer: any table with a heading row; stock lists, attendance registers (one column per day, or one row per person and day) and general tables get their own dashboards. 3PL Invoice Audit: the detailed invoice export with at least a line amount; a rate card and an operational export are optional and add checks.
No. They are read inside your browser tab and discarded when you close it; reports are created in the browser and saved to your device. No account is needed for the tools.
Results have been checked on synthetic data only, and the Excel reports have been checked in LibreOffice, not yet in Microsoft Excel. Nothing is saved between visits: column choices, review notes and results go when you close the tab, so download the report (the 3PL Invoice Audit can keep column choices and audit summaries in your own browser if you switch that on). The tools never change your stock system or ERP, and a difference between two figures is shown as a difference to check, never as proof of loss or error. They work best in a current Chrome or Edge on a computer.
Yes. Each tool has a button that loads invented sample files.
