CSV Files to Wix Migration

Step-by-Step Guide to Importing CSV Files into Wix

Step 1. Prepare Your Data and Connect Wix

Prepare the data you want to migrate, such as products, product categories, and customers. Use separate files for each data type where possible. If an export is split into multiple files, you can upload the parts together.

Sign in to the LitExtension app, open New Migration, and select Files (CSV, Excel, Google Sheets) as the Source Cart Type.

Add your data using one or more of these methods:

• File Upload: Upload CSV, TSV, XLSX, or XLSM files. You can add up to 50 files, with a maximum size of 50 MB per file.
• Google Sheets: Set sharing to Anyone with the link can view, open the tab you want to import, and copy its URL. Each link reads one tab, so add a separate link for each additional tab.
• Link: Add a public link to an individual CSV or Excel file from Dropbox, Google Drive, or OneDrive. The link must open the file without requiring a login.

Review the uploaded-file list and check the File, Data Type, and Rows columns. Correct any incorrectly detected data type. If the same product or customer appears in multiple files, the system uses the record from the file listed first.

Make sure image URLs are publicly accessible. Add the optional Old Store URL if your files contain relative image paths, such as /images/product.jpg, or if you need supported redirect options.

Select Wix as the Target Cart Type, enter the required store details, and follow the connection instructions. Save a backup of any existing Wix data you need to keep, and pause automated customer emails or workflows that imported records could trigger. Once the target store is connected, continue to Prepare Data.

Step 2. Map Your Fields, Check Your Data, and Configure the Migration

Review Field Mapping to match the columns in your files to the corresponding Wix fields. LitExtension automatically maps recognized file formats. Use the record previews to check the mapped values and adjust any incorrect matches.

Select the correct Product Identifier so rows belonging to the same product are grouped with their variants and images. Check product names, SKUs, prices, quantities, image links, and the fields used to associate related records.

For customers, choose an available ID, email, or phone column as the Customer Identifier. Deselect fields you do not want to migrate. Specialized fields also need usable source values and a compatible available mapping; a column label alone does not establish working target behavior.

Use AI Mapping Suggestions if unfamiliar column names make mapping difficult.

Click Next: Data Check to save the mapping and validate the entire dataset. Data Check does not transfer data.

Review the results before continuing. The summary shows the records that are Ready to import, along with Skipped records and Errors / Duplicates. Each issue is marked by level:

• Error: The affected record is not imported.
• Warning: The record is imported but should be reviewed.
• Info: Information only.

Choose how to handle records with errors: Skip those records and continue, or Stop the migration until fixed.

To correct problems, download the Results File, review the status information for each row, fix the affected records, and replace the uploaded file. Then click Check Again.

If you edited a file accessed through a shared link, use Refresh link or add the link again before checking the data. The system downloads linked files when they are added, so later edits are not picked up automatically.

Run Data Check again whenever you change a file, Google Sheet, or mapping. The system requires an up-to-date check before migration can start.

Once the data is ready, open Configuration. Select the supported data types you want to transfer to Wix, such as products, product categories, and customers. Reviews are not currently supported through Files Migration.

Choose the additional options available for your migration. Check the selected data types and settings, confirm that you have reviewed the configuration, and click Next: Start Free Demo Migration.

Step 3. Run a Demo, Review the Results, and Run Full Migration

The free demo transfers a small sample of records to Wix. Keep the source files and Google Sheets unchanged while it runs. You can close the page, and LitExtension sends an email when the demo finishes.

When the demo finishes, use View to inspect the migrated records in your Wix dashboard. Compare them with the source files and check:

• Products: Names, SKUs, prices, special prices, variants, quantities, and images.
• Product Categories: Names, descriptions, and images.
• Customers: Names, email addresses, and billing addresses.

Verify the results of any additional options you selected. If you enabled redirects, open sample old URLs and check that they lead to the correct Wix pages. Where relevant, also check cleaned names, images embedded in descriptions, and the result of any target data cleanup.

If you find incorrect or missing information, return to the source data or Field Mapping, make the necessary changes, run Check Again, and select Demo Again.

Once the demo results are correct, click Next: Confirm Orders, review the price, complete payment, and start Full Migration. This transfers all selected records eligible after Data Check. If the source data or mapping has changed, the system requires another check before payment.

Track progress in My Migrations. You can close your browser and return to check the migration later. Keep the required Wix access and image links available until the transfer is complete. LitExtension sends an email when the migration finishes.

After completion, compare the migrated record counts with the eligible records from Data Check and review representative products, categories, and customers. Check their values, images, and relationships, then test the relevant customer journeys in your Wix store.
