Split large datasets into smaller chunks or separate files with various splitting options
Upload a dataset and split it into smaller, manageable chunks
Drag & drop a CSV or JSON file here, or click to select
Supports CSV and JSON files up to 50MB
Upload your CSV or JSON file using the drag-and-drop area, then select your preferred splitting method (by rows, chunks, columns, or size). Configure the split parameters, click 'Split Data', and download the resulting chunks individually or all at once.
The Data Splitter tool supports CSV (Comma-Separated Values) and JSON (JavaScript Object Notation) files. Both formats are commonly used for data exchange and storage, and the tool handles them with full preservation of data structure.
The tool offers four splitting methods: 1) Split by Rows - divide data into chunks with a specific number of rows each, 2) Split into Chunks - divide into a specific number of equal chunks, 3) Split by Columns - separate selected columns into different files, and 4) Split by Size - divide based on approximate file size in KB.
Split by rows divides your dataset into multiple files, each containing a specified number of rows. For example, if you have 1000 rows and set 100 rows per chunk, you'll get 10 separate files. This is useful for breaking down large datasets into manageable portions.
Yes! The column splitting feature allows you to select specific columns to separate into one file, while the remaining columns go into another file. This is useful for data separation, privacy concerns, or creating focused datasets with only relevant columns.
All data splitting is performed entirely in your browser using JavaScript. No data is uploaded to servers or transmitted anywhere. Your files remain completely private and secure on your device. The tool processes everything client-side for maximum privacy.
After splitting, you can download each chunk individually by clicking the download icon on each result card, or use the 'Download All' button to batch download all chunks at once. Each file is automatically named with a descriptive identifier based on your splitting method.
The tool supports files up to 50MB in size. For most use cases, this is sufficient for hundreds of thousands of rows of data. Since processing is done in your browser, very large files depend on your device's available memory and processing power.
