Restructuring .json data as .qts 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.
A Qt Linguist translation source — catalogued here as .qts — is the XML file a Qt application is translated in: a <TS> document holding <context> groups, each containing <message> elements that pair a <source> string with its <translation>. Qt names these files .ts, which collides with TypeScript, so Novus Convert recognises them by the .qt.ts suffix and files them under .qts to keep the two apart. For this route the practical draw is context grouping gives translators genuine information about where a string appears and review state and obsolete strings are typed attributes, not conventions — balanced against the .ts extension collides with TypeScript, which breaks naive tooling constantly, which is worth knowing before you commit a large batch.
Why convert JSON to QTS?
The practical trigger for this conversion is usually a mismatch: with .json, no comments — a perpetual annoyance for configuration files. Switching to .qts buys you context grouping gives translators genuine information about where a string appears, which is why it is the better fit for translating a Qt or KDE desktop application. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
JSON vs QTS at a glance
| Aspect | JSON data (.json) | Qt Linguist TS (.qts) |
|---|---|---|
| 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 | the root <TS> element carries a version and the target language; <context> groups messages under a <name>, conventionally the class that contains them |
| Strongest at | rEST and HTTP API request and response payloads | translating a Qt or KDE desktop application |
| Weak spot | no comments — a perpetual annoyance for configuration files | the .ts extension collides with TypeScript, which breaks naive tooling constantly |
Pick QTS as the output
Select .qts in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if QTS 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 QTS file. Outputs keep the original filename with the .qts extension.
JSON to QTS questions, answered
Will converting JSON to QTS lose quality?
There is no visual quality to lose — json is text-oriented and qts 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 QTS file work?
Qt Linguist, Qt Creator and KDE's Lokalize read .ts natively, and the larger translation platforms support it. Elsewhere it is rarely recognised — and the extension collision means generic tools frequently mistake it for TypeScript. Novus Convert keys entries on the source text, rejects documents with a doctype or custom entities, and converts to and from the other localization formats.
Will the QTS file be bigger or smaller than my JSON?
It depends on the content: the root <TS> element carries a version and the target language; <context> groups messages under a <name>, conventionally the class that contains them. Convert one representative file first and compare before batch-processing a large set.
