Network Graph Visualizer

ReadyHow to use

Draw a node-link graph from an edge list, with clusters and degree metrics.

Free to use. No account, no daily limit, and no backend processing for tool input.

Tip: use samples, upload, copy, download, and send-to actions inside the workspace where available.

What is Network Graph Visualizer?

Network Graph Visualizer is a free, browser-based tool that helps you convert between formats. Draw a node-link graph from an edge list, with clusters and degree metrics. It's built for speed and privacy: Everything runs locally in your browser — your data is never uploaded to a server. No sign-up, no installs, and no daily limits.

How to use Network Graph Visualizer

1Paste your data into the input panel, or drag-and-drop a file (you can also load a built-in sample).
2Adjust the conversion options — delimiter, formatting, and field handling — to match your data.
3Review the result in the output panel and copy it or download it as a file.

Features

Auto-detects delimiters and structure
Round-trips cleanly between formats
100% client-side — no upload, fully private
Free with no account, no watermark, and no daily limit
Works on large inputs, limited only by your device's memory
Load a sample, then copy, download, or share your result

Common uses

Building a quick chart for a report or slide
Quick one-off converter jobs without opening a heavy app
Preparing data before importing it elsewhere
Sharing a reproducible result with a teammate via a link

Used by

Data analysts
Product teams
Students
Researchers
Data migration teams
Integration engineers

Common errors

Headers or keys are not consistent across records.
Delimiter, quote, or encoding settings do not match the source file.
Nested fields need flattening before the result works as a table.
Blank values are mistaken for zeros or real values instead of remaining explicit.

How it works

1Reads the data input in the browser.
2Maps fields into the target structure.
3Renders a preview and exportable output.

Recommended workflow

1
Prepare the input
Start with the source file or pasted payload, then confirm delimiters, headers, and field handling before conversion.
2
Run Network Graph Visualizer
Review the preview, copy or download the result, and keep everything local in your browser.

Frequently asked questions

How do I use Network Graph Visualizer?: Paste or drop your data into the workspace, adjust the options to fit your data, then copy or download the result. Draw a node-link graph from an edge list, with clusters and degree metrics.
Is my data uploaded or stored anywhere?: No. Everything runs locally in your browser — your data is never uploaded to a server. Nothing is sent to a server, so it's safe to use with private or sensitive data.
Is Network Graph Visualizer free?: Yes — it's completely free with no account, no sign-up, no watermark, and no daily usage limits.
What's the maximum file size?: There's no hard limit imposed by the tool. Because processing happens in your browser, the practical ceiling is your device's available memory — most everyday files work instantly.
Do I need to install anything?: No installs and no extensions — it runs entirely in your web browser and even works offline once the page has loaded.
