See which prices went up

A new price list landed. Load it beside the one you have been buying against and see everything that changed.

What this catches

  • Prices that went up, old figure beside new
  • Lines that were discontinued since the last list
  • New lines that were not offered before
  • Codes listed twice at different prices

You will be asked which column identifies a row. Usually the product or SKU code.

File A · original

Drop a CSV or XLSX file here, or click to browse

File B · updated

Drop a CSV or XLSX file here, or click to browse

All file data is read entirely within this browser tab. Nothing is uploaded to any server. Closing this tab discards all loaded data.

How it works

  1. Find the price list you have been buying against, and the new one.
  2. Load the old list on the left and the new list on the right.
  3. Pick the product or SKU code as the column that identifies a row.
  4. Changed rows are the price moves; removed rows are discontinued lines; added rows are new ones.

Questions

How do I compare two supplier price lists?
Load the old list and the new one, then pick the product or SKU code as the identifying column. Every line is sorted into matched, changed, added, removed or duplicate, and each changed price is shown with the old figure beside the new one.
Will it tell me how much each price moved?
It shows the previous value beside the current one for every changed field, so the movement is visible per line. It does not calculate percentages for you — export the changed rows if you want to work them out in a sheet.
How do I see what was discontinued?
Anything in the old list with no match in the new one is counted as removed, which is exactly the discontinued set. New lines appear as added.
Is my file uploaded anywhere?
No. Both files are read and compared inside this browser tab. Nothing is sent to a server, there is no account, and closing the tab discards everything.
What file formats does it accept?
CSV and XLSX. Both sides can be different formats — a CSV against an XLSX works.
How large a file can it handle?
It has been measured on 100,000 rows a side. Large files take a few seconds to parse, and the comparison itself runs in well under a second.
Can I export the differences?
Yes. The result can be exported as CSV or XLSX, so you can attach it or keep it with the period’s paperwork.
