A LITTLE HELP AT YOUR DESK
Keep the details.
Clear the confusion.
Start with the issue below, or follow the comparison guide and sample files. Keep your original spreadsheets unchanged while you review a comparison.
A spreadsheet will not load
Choose CSV, TSV, XLSX or XLS. Text files must be UTF-8. Password-protected workbooks and PDF/OCR input are not supported. Use up to five files, each no larger than 10 MB, with at most 5,000 data rows, 80 columns and 20 sheets. For a CSV quote error, open the file in your spreadsheet application and export it as UTF-8 CSV again. For a large workbook, save only the required price-list sheet.
My products are not joining
Declare shared product IDs only when both files use the same catalogue. Supplier-specific codes are not automatically the same product. Duplicate IDs and conflicting specifications need review. Similar names remain suggestions until you confirm identity. The row editor lets you keep items separate, and Undo reverses your last change.
The unit price looks unexpected
Enter the price of the complete pack and its full quantity. Six 500 g bags contain 3,000 g, not six grams. Check the declared decimal convention and currency. US and imperial gallons are separate units; mass cannot become volume without density. Missing prices remain missing. The unit-price calculator shows the arithmetic for one pack.
Freight or tax changes my decision
Comparison unit prices exclude freight, tax and minimum-order effects. Use the whole-pack cost calculator for an explicit scenario. Enter zero only for a charge that does not apply; unknown costs are not zero. Its disclosed tax and duty bases may differ from those for your purchase.
A currency is missing from the reference converter
The dated ECB snapshot has limited coverage and is not a live transaction quote. It excludes KWD and other GCC currencies. The comparison desk can use an exchange rate you explicitly supply. Check the direction carefully: the rate states how much report currency one unit of the source currency buys.
My PDF does not support a character
The report font supports tested Latin and Arabic content, not every writing system. Use the Excel report or CSV bundle when PDF warns about unsupported characters. Excel contains comparison, assumptions and source-evidence sheets. CSV downloads are three separate raw-data files. All exports include every product, even when a filter is active.
Can I recover a closed comparison?
Unsaved work clears on refresh or close. A comparison explicitly saved with Save on this device can be reopened from Saved projects & profiles in the same browser profile and site address. Download backup JSON preserves saved projects, versions and profiles; Restore backup imports copies without overwriting existing projects. Browser cleanup or private browsing can remove saved work. A backup is not cloud sync. Read exactly what stays local and what hosting requests expose.
