How to use JSON Splitter Online to divide files into chunks
Use this JSON file splitter to paste or upload an array, choose the split strategy, and preview each chunk before downloading.
1
Paste or upload a JSON file into JSON Splitter
Start with a valid JSON array. JSON Splitter is built for list-style datasets such as API payloads, exports, catalogs, or event logs that you need to split online.
Array-first workflow - Use JSON Splitter to paste array data, upload a JSON file, or load sample data.
Instant preview - JSON Splitter updates chunk results as soon as the JSON is valid.
JSON Array Example
[
{ "id": 1, "name": "Product A", "price": 29.99 },
{ "id": 2, "name": "Product B", "price": 49.99 },
{ "id": 3, "name": "Product C", "price": 19.99 },
{ "id": 4, "name": "Product D", "price": 99.99 },
{ "id": 5, "name": "Product E", "price": 39.99 }

Choose how JSON Splitter splits your file
With JSON Splitter, switch between chunk-count mode and items-per-chunk mode depending on whether you want to split a JSON file into multiple files inside a ZIP or keep each slice a fixed size.
Number of chunks - Use JSON Splitter to split an array into a target number of nearly equal chunks.
Items per chunk - With JSON Splitter, keep each chunk capped at a consistent number of items.
Chunk Preview Example
Chunk 1 (3 items)
[
{ "id": 1, "name": "Product A", "price": 29.99 },
{ "id": 2, "name": "Product B", "price": 49.99 },
{ "id": 3, "name": "Product C", "price": 19.99 }

Preview and export chunks with JSON Splitter
In JSON Splitter, use the chunk tabs on the right to inspect each result, download the active chunk, or export all chunks as separate JSON files inside one ZIP archive.
Chunk navigation - In JSON Splitter, jump between chunk tabs and verify item counts before exporting.
Focused export - JSON Splitter lets you download the current chunk or package all chunks into a ZIP archive.
Export one chunk or a ZIP archive
3 Actions
Download
Export the active chunk as its own JSON file
ZIP
Export all chunks as separate JSON files
Copy
Copy the active chunk to your clipboard
Tip: ZIP export is helpful when a workflow needs every chunk saved as its own JSON file.
JSON Splitter FAQs
Common questions about splitting large JSON files
The JSON Splitter breaks a JSON array or uploaded JSON file into smaller valid JSON array chunks. You can split by choosing how many chunks you want overall, or by setting how many items should go into each chunk. It is useful for batch processing, data migration, API uploads, and previewing large datasets in smaller pieces.
Yes. Upload or paste a JSON array, choose the number of chunks or items per chunk, then export all chunks as separate JSON files inside one ZIP archive. The split happens in your browser, so your JSON file is not uploaded to a server.
Number of chunks divides the input array into a target number of nearly equal parts. Items per chunk keeps each chunk at your preferred size, with the last chunk holding the remainder. Both modes preserve valid JSON arrays and update the preview instantly.
Not with the current splitter workflow. This tool is intentionally optimized for JSON arrays, because chunk navigation and item counts only make sense when the input is a list. If your JSON is an object, wrap the records you want to split inside an array first.
No. Everything runs in your browser. Your JSON stays on your machine, so the tool is safe for internal datasets, API responses, and private records you do not want to upload anywhere.
The splitter caps the number of chunks at the number of items. For example, a 5-item array split into 10 chunks becomes 5 chunks with one item each. This avoids empty chunks and keeps the output predictable.
Yes. The right panel always shows one active chunk at a time, and the Download button exports that current chunk as its own JSON file. You can also open the Download menu and export all chunks together as a ZIP file.
Sample loads a compact product dataset so you can immediately test the splitter workflow, switch chunk tabs, and see how the output changes between chunk-count mode and items-per-chunk mode.
