Frequently asked questions
- Does this sort arrays too?
- No — only object keys are sorted. Array element order is preserved, since arrays are often ordered lists (steps, a queue, coordinates) where reordering would change their meaning.
- Why would I want to sort JSON keys?
- It's most useful before diffing two JSON files — if one was generated with keys in a different order but the same data, a plain text diff shows every line as changed. Sorting both first makes the diff show only real differences.
- Is sorting recursive?
- Yes — every nested object in the document has its keys sorted, not just the top level.
- Is my data uploaded anywhere?
- No — sorting happens entirely in your browser. Nothing is uploaded.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online tools |
|---|---|---|
| Data ever leaves your device | No — sorted in this tab | Yes, uploaded to process |
| Sorts nested objects recursively | Yes | Varies — some tools only sort the top level |
| Account required | Never | Often, past a certain usage level |
