CSV Splitter

What is the CSV Splitter?

Handling massive CSV files can be difficult. They might be too large to open in Excel, too heavy to upload to an API, or simply unwieldy to manage. The CSV Splitter helps you break these monoliths down into smaller, bite-sized files.

It offers two powerful modes:

1. Split by Row Count: Perfect for batching. E.g., "Give me files with 1000 rows each."
2. Split by Column: Perfect for categorization. E.g., "Create a separate file for every 'Department' found in the list."

Key Features

• Row Partitioning: Precise control over file size by specifying the maximum rows per output file.
• Column-Based Grouping: Intelligent splitting that analyzes your data and groups rows by value (e.g., separating "USA" customers from "UK" customers).
• Auto-Naming: Output files are automatically named for easy identification (e.g., split_part_1.csv or split_sales_dept.csv).
• Archive Generation: Download individual parts instantly.
• Browser Performance: Processes data locally, making it ideal for splitting sensitive files securely.

How to Use

1. Input Data: Paste your large CSV content into the editor.
2. Choose Mode:
   • Split by Row Count: Enter the desired number of rows per file.
   • Split by Column Value: Select the target column (the header dropdown will populate automatically).
3. Process:
   • Click "Split CSV".
   • The tool will generate a list of result files.
4. Download:
   • Download the specific chunks you need from the results list.

Use Cases

• Email Marketing limits: Split a 50,000-contact list into chunks of 5,000 to meet your daily sending quotas.
• Regional Analysis: Split a global sales report into separate files for each "Country" or "Region" manager.
• File Upload Limits: Break a 100MB file into smaller parts to bypass upload restrictions on other platforms.
