Important: an update should not normally remove your data, but you should always take a full backup first. If the website uses custom CSS, custom JavaScript, legacy theme overrides, or old jQuery integrations, treat the update to 3.x as a controlled migration and test it in staging before touching production.
The safest update workflow is:
- Create a full backup of database, uploads, and plugin files.
- Clone the website to staging.
- Install the new plugin version in staging.
- Test real calculators on real products, including product page, cart, checkout, and order data.
- Only after validation, repeat the update in production.
Update from WordPress admin
- Download the latest version from your download area.
- In WordPress admin, open Plugins.
- Deactivate YourPlugins Spreadsheet Calculator Pro.
- Delete the old plugin package from WordPress admin.
- Go to Plugins > Add New.
- Click Upload Plugin and select the new ZIP file.
- Install and activate the new version.
Update by FTP
- Download the latest version from your download area.
- Extract the ZIP file locally.
- Overwrite the files in
/wp-content/plugins/excel-worksheet-price-calculation.
After updating, clear any cache or CDN layer, then test at least one important calculator from product page to checkout.
