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.
Restructuring .json data as .gexf changes the serialization without touching the values themselves. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Restructuring .json data as .gexf 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 .gexf file is Gephi's graph interchange format: XML describing nodes and edges with attributes, and — unlike most graph formats — with first-class support for visual properties and for graphs that change over time. For this route the practical draw is native visual and temporal modelling, which most graph formats omit entirely and clean, readable XML that maps closely to how Gephi thinks about graphs — balanced against support outside Gephi and its ecosystem is thinner than GraphML's, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .json, no comments — a perpetual annoyance for configuration files. Switching to .gexf buys you native visual and temporal modelling, which most graph formats omit entirely, which is why it is the better fit for saving and sharing Gephi network visualisations with their styling intact. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | JSON data (.json) | Graph Exchange XML Format (.gexf) |
|---|---|---|
| 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 graph element's mode attribute is static or dynamic; dynamic graphs attach start and end times to nodes and edges |
| Strongest at | rEST and HTTP API request and response payloads | saving and sharing Gephi network visualisations with their styling intact |
| Weak spot | no comments — a perpetual annoyance for configuration files | support outside Gephi and its ecosystem is thinner than GraphML's |

Select .gexf in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if GEXF is selectable, the route is real and validated.
Press Convert. The restructuring is plain local parsing — your data is never posted to a server for processing.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid GEXF file. Outputs keep the original filename with the .gexf extension.
There is no visual quality to lose — json is text-oriented and gexf 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.
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.
Gephi, NetworkX, igraph, sigma.js and Cytoscape (via plugins) read GEXF. Novus Convert normalises topology and labels locally without network access or external entity expansion, and converts to GraphML, DOT, JSON and SVG. Visual and temporal attributes are not carried into the targets, none of which can represent them.
It depends on the content: the graph element's mode attribute is static or dynamic; dynamic graphs attach start and end times to nodes and edges. Convert one representative file first and compare before batch-processing a large set.
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .json → .gexf → .json is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
