CSV Tools
CSV Splitter
Split large ecommerce CSV files into smaller chunks while preserving headers.
Who this tool is for
Catalog teams and operators preparing imports for systems with file-size or row limits.
How it works
Upload one CSV, choose rows per file, then download generated split files from your browser.
Private by design
Private by design: this tool runs in your browser. Your Shopify CSV is processed locally and is not uploaded to our servers. No Shopify login, no Shopify API connection, and no account required.
FAQ
Does splitting keep the header row?
Yes. Every generated file includes the original header row.
Can I choose chunk size?
Yes. Set rows per file before downloading the split output.
Is a ZIP file generated?
Yes. You can optionally export all split files as a single ZIP in the browser.
