CSV to JSON FREE

Columns
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
The header row becomes the keys. Duplicate and empty column names are made unique rather than allowed to overwrite each other, because a spreadsheet with two "Notes" columns is common and silently keeping only the second one loses a column of data.
Type conversion is a choice, and it is off by default. Turning "007" into the number 7 and "1-2" into a date is how a converter quietly corrupts a product catalogue; when you turn it on, numbers, booleans and null are converted and everything else stays a string.
The preview shows the first rows as the parser read them, so you can check the delimiter and the header row before converting two hundred rows on faith. Everything happens in your browser.

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.
