What is Shopify's CSV import row limit?

Shopify's product CSV importer supports up to 1,000 rows per import file. For larger catalogs, you need to split the file and import each chunk separately.

Will the header row be included in every chunk?

Yes. Every output file includes the original header row. This is required by most ecommerce import tools to correctly map columns.

Can I use this for order exports, not just product catalogs?

Yes. Any CSV file — products, orders, customers, inventory — can be split by row count. The tool does not interpret the content, only the row structure.

Does splitting change any product data or SKUs?

No. The tool only divides the file — it does not modify, reorder, or transform any cell values including SKUs, prices, or descriptions.

Split Product & Order CSVs Into Chunks for Bulk Ecommerce Uploads

Shopify's product CSV importer caps bulk uploads at 1,000 products per file. WooCommerce and most marketplace feed tools impose similar limits. When you export a 10,000-SKU catalog or a month of orders, you cannot upload the raw file — you have to split it first.

E-commerce managers dealing with large catalog updates, inventory syncs, or order exports face this problem constantly. Manually splitting a spreadsheet in Excel is error-prone: it is easy to accidentally omit the header row, miscount rows, or corrupt data when copy-pasting across files. A purpose-built split tool eliminates those errors entirely.

Deliteful splits your product or order CSV into fixed-size chunks with the header row automatically included in every output file. Set your limit to 1,000 for Shopify, 2,000 for WooCommerce, or whatever your platform requires — then download the numbered chunks and upload them in sequence.

How it works

1
Export your catalog or order CSV
Download the full product, inventory, or order CSV from your ecommerce platform or ERP.
2
Set the row limit for your platform
Enter 1,000 for Shopify product imports, or check your platform's documentation for its specific bulk upload limit.
3
Upload each chunk to your platform
Download the sequentially numbered output files and import them one by one — each includes the header row your importer expects.
