Add your JSON file
Drop one or more .json files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
JSON to M3U
Restructuring .json data as .m3u changes the serialization without touching the values themselves. Free, private, and validated — the file never leaves your browser.

Restructuring .json data as .m3u changes the serialization without touching the values themselves. A .json file holds JavaScript Object Notation: nested objects, arrays, strings, numbers, booleans, and null written in a strict text syntax. It is the default data language of the web — most APIs speak nothing else.
An .m3u file is a playlist: an ordered list of media file paths or URLs, one per line, optionally annotated with #EXTINF lines carrying each track's duration and title. It contains no audio itself — only pointers to it. For this route the practical draw is trivially simple — readable and editable in any text editor and supported by effectively every media player ever written — balanced against unspecified encoding causes mojibake in non-ASCII track names, which is worth knowing before you commit a large batch.
Why convert JSON to M3U?
The practical trigger for this conversion is usually a mismatch: with .json, no comments — a perpetual annoyance for configuration files. Switching to .m3u buys you trivially simple — readable and editable in any text editor, which is why it is the better fit for saving a local playlist from a media player. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
JSON vs M3U at a glance
| Aspect | JSON data (.json) | M3U playlist (.m3u) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | exactly six value types; no dates, no comments, no trailing commas — the strictness is deliberate | plain lines are media references — relative paths, absolute paths or URLs — in playback order |
| Strongest at | rEST and HTTP API request and response payloads | saving a local playlist from a media player |
| Weak spot | no comments — a perpetual annoyance for configuration files | unspecified encoding causes mojibake in non-ASCII track names |
Pick M3U as the output
Select .m3u in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if M3U is selectable, the route is real and validated.
Convert on your device
Press Convert. The restructuring is plain local parsing — your data is never posted to a server for processing.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid M3U file. Outputs keep the original filename with the .m3u extension.
JSON to M3U questions, answered
Will converting JSON to M3U lose quality?
There is no visual quality to lose — json is text-oriented and m3u is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Is it private to convert JSON files here?
Yes — the .json file is processed inside your browser tab and never uploaded. The restructuring is plain local parsing — your data is never posted to a server for processing. Close the tab and the file is gone from memory.
Where will the M3U file work?
Read by VLC, foobar2000, iTunes, Winamp and essentially every player and car stereo. The encoding ambiguity is the practical problem, not support. Novus Convert parses it locally and converts to M3U8 and JSON, which is the reliable way to force UTF-8 onto a legacy playlist.
Will the M3U file be bigger or smaller than my JSON?
It depends on the content: plain lines are media references — relative paths, absolute paths or URLs — in playback order. Convert one representative file first and compare before batch-processing a large set.
Can I convert M3U back to JSON?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .json → .m3u → .json is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
