Batch-converting XML to JSON (50+ files at once)
How to convert a whole folder with XML to JSON Converter without uploading anything. Browser-based, free, no signup, runs entirely on your device.
Doing one JSON document at a time is fine. Doing 50 of them is a different problem entirely — and exactly where most browser tools fall apart. XML to JSON Converter handles batches by design, processing them through the same in-browser pipeline as single files without re-uploading anything.

The batch workflow
- Open XML to JSON Converter.
- Select all the JSON documents at once. Drag a whole folder onto the drop area, or use Ctrl/Cmd+A in the file picker.
- Set the options once — they apply to every JSON document in the batch.
- Start the run. XML to JSON Converter processes them sequentially; progress shows file-by-file completion.
- Download — usually a single ZIP with every result inside, named after the original JSON documents.
How long does a batch take?
Roughly the same time as one JSON document, multiplied by the count. A small JSON document processes in well under a second; 50 of them take under a minute. Larger JSON documents (video, scanned PDFs) scale linearly — budget a few seconds per file. Your CPU is the limit, not the network, because nothing is being uploaded.
Memory and browser limits
XML to JSON Converter stages the work so the browser only holds a few JSON documents in memory at once, not all 50. This means you can safely batch hundreds of files on a normal laptop — the limit is your patience, not the browser's RAM.

When batching saves real time
Examples where batch processing pays off:
- Wedding photo cleanup — a thousand-image album, processed at once, downloaded as a single ZIP.
- Monthly invoice archive — every PDF for a year, compressed and stripped of metadata in one pass.
- Bulk format conversion — every HEIC photo from a trip, converted to JPG for sharing.
- Document scan run — a folder of scanner output, all run through the same cleanup, all named consistently.
Frequently asked questions
Does the ZIP download work on mobile?
Yes — both iOS and Android handle ZIPs from browser downloads. You can extract them with the built-in file manager.
Are batches faster than processing files one at a time?
Slightly faster end-to-end because there's no re-initialisation between files. But the big win is your time, not CPU time.
Will all files in the batch get the same settings?
Yes — that's the whole point of batching. If you need different settings per file, run them in separate batches.
What if one file in the batch fails?
XML to JSON Converter skips the failed file, continues with the rest, and reports the error at the end. You can re-run just the failed one separately.
