Introduction
Have you ever encountered a file size error when importing blogs or products into Shopify? Simply put, you can easily split your files into appropriate sizes (approx. 500KB) directly in your browser using our “XML Splitter” and “CSV Splitter” tools.
This prevents timeouts and memory errors, allowing for a safer data migration process.
Why File Splitting is Necessary
When migrating data from a large-scale site, exported files (XML or CSV) can reach several megabytes or even dozens of megabytes. However, Shopify’s import functions and many apps have the following limitations:
- Size Limits: Shopify’s standard import and some apps have file size restrictions (e.g., 500KB or 2MB).
- Timeouts: If a file is too large, server-side processing may time out, causing the import to stop midway.
- Memory Errors: Analysis of the file itself may fail due to browser or server memory shortages.
To solve these issues, you need to split your data into “manageable, small units” beforehand.
Solutions with Free Tools: Two Splitters
Blog Importer provides two types of free splitting tools depending on your needs:
1. WordPress XML Splitter
Splits XML (WXR format) files exported from WordPress.
- Features: Instead of simple text splitting, it analyzes the WordPress data structure and splits by “Post” units.
- Maintain Integrity: Automatically inserts common headers like “Author Information” and “Category Definitions” into each split file, preventing errors during import.
2. CSV Splitter
Splits Shopify import CSV files or general-purpose CSV files.
- Features: Recognizes the Header (Column Names) on the first line and automatically replicates/adds it to all split files.
- Optimization: Automatically adjusts to “approx. 500KB,” which is the most stable size for processing in Blog Importer.

Frequently Asked Questions (FAQ)
Q. Is there a specific order for loading the split files? A. No, the order doesn’t matter. Since each file contains all the necessary information, they can be imported correctly in any order.
Q. I’m worried about uploading data to a server. A. Don’t worry. This tool is browser-based. All files are processed entirely within your browser and are never sent to our servers.
Q. Will images be migrated correctly after splitting? A. Yes. The image URLs within the XML or CSV are preserved as they are, and will be automatically collected/replaced when importing with the Blog Importer app.
