How to use JSON Splitter to divide arrays into chunks
Use JSON Splitter to paste an array, choose the split strategy, and preview each chunk before downloading.
1
Paste a JSON array 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.
Array-first workflow - Use JSON Splitter to paste array data directly into the editor 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 array
With JSON Splitter, switch between chunk-count mode and items-per-chunk mode depending on whether you care more about the number of files or the size of each slice.
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, then copy or download only the chunk you need without downloading all results.
Chunk navigation - In JSON Splitter, jump between chunk tabs and verify item counts before exporting.
Focused export - JSON Splitter lets you download or copy the current chunk instead of a giant wrapper object.
Export one chunk at a time
2 Actions
Download
Export the active chunk as its own JSON file
Copy
Copy the active chunk to your clipboard
Tip: chunk-by-chunk export is helpful when you are testing uploads or processing data in batches.
JSON Splitter FAQs
Common questions about splitting large JSON files
The JSON Splitter breaks a JSON array 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.
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 switch between chunk tabs and download exactly the slice you need.
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.
