Shopify Price Updater

About this tool

The Shopify Price Updater rewrites the prices in a product CSV export in bulk. Raise every price by 10%, knock $5 off for a sale, and snap the results to .99 endings — without touching a spreadsheet formula.

It targets the "Price" column by default ("Variant Price" in older files), skips empty or non-numeric cells, and preserves every other column and row exactly, so the file stays ready to re-import. Everything runs in your browser, so the file never leaves your device.

How to use it

2. Set the price changePick a percentage or fixed amount, increase or decrease, and an optional rounding rule like .99 endings.
3. Download and re-importThe updated CSV is ready instantly — check the summary, download it, and import it back into Shopify.

Frequently asked questions

Which column does it update?

The "Price" column by default, or "Variant Price" in files that use Shopify's older headers. You can switch to any other column, like "Compare-at price" ("Variant Compare At Price" in older files), before running the update.

What happens to empty or non-numeric price cells?

They are left untouched and counted as skipped in the summary. A cell like "n/a" or a blank variant row will not break the update.

How does .99 rounding work?

After the change is applied, each price moves to the nearest value ending in .99 (or .95, or a whole number, depending on the rule). For example, $10.40 becomes $9.99 and $10.60 becomes $10.99.

Will it change anything else in my CSV?

No. Only the price column is rewritten — every other column and row is preserved exactly as it was, so the file stays importable.

Can I check what changed before importing?

Yes. Download the updated file and compare it against your original with the Shopify CSV Diff tool to see every price that moved.

Is my data uploaded anywhere?

No. The file is read and updated entirely in your browser — nothing is sent to a server.
