JSON to CSV FREE
Flatten an array of JSON objects into a CSV table. Nested values are either flattened into dotted columns or reported, never silently dropped.

CSV, TSV, JSON, YAML, XML, Markdown, HTML, plain text, Excel workbooks, and audio and video. The format is read from the file itself, not from its name.

Uncheck a column to leave it out, type over a name to rename it, and use the arrows to reorder. The preview below follows.

How this conversion works
A CSV is a rectangle and JSON is a tree, so the interesting question is what happens to the branches. This converter gives you two honest answers: flatten nested objects and arrays into dotted columns (user.name, user.tags.0), or stop and name the paths that will not fit.
What it never does is the third thing most converters do, which is to stringify a whole nested branch into one cell of unreadable JSON, or drop it in silence. Either way you would find out later, from the spreadsheet.
An array of objects converts directly. A document with a single wrapper key holding the array - the shape almost every API returns - is unwrapped automatically. A document that is one object with no list in it has nothing to put in rows, and says so.

MCP, Model Context Protocol: what it is and how it works in practice
Model Context Protocol, or MCP, is an open standard for connecting AI applications to tools and data sources. Instead of building a separate integration for every model and service, an MCP server describes its capabilities in a standardized form that compatible clients can discover and invoke. By 2026, MCP has moved well beyond its original release: the current specification uses a stateless HTTP core, formal extensions, stronger authorization rules, and mechanisms for long-running work.
Axios vs Fetch and Ky: Which HTTP Client Should You Use?
Axios became the default HTTP client for many JavaScript teams because it offered a clean API before Fetch became the standard browser primitive. Today, many teams can use native Fetch directly or pick Ky, a small wrapper that adds convenience without the full weight of Axios. The right choice depends on whether you actually need Axios-specific features such as interceptors and existing wrappers, or whether a lighter, more modern request layer fits your app better.
Redux Toolkit vs Zustand: Which State Library Is Better?
Redux Toolkit is the modern standard for writing Redux logic and remains a strong choice for large applications with strict patterns. Zustand is a smaller, simpler state management library with a hooks-first API and much less boilerplate. The decision is not about which library is more popular. It is about whether your team needs explicit enterprise structure or a lightweight store that stays out of the way.
