🚀 CSV + JSON Editor for Developers

A fast, developer-first CSV editor with built-in JSON intelligence — designed for real-world data workflows.

⚡ Why this exists

Editing CSVs in VS Code usually means:

• ❌ Poor performance on large files
• ❌ No support for structured data inside cells
• ❌ Constant switching to Excel or external tools

This extension fixes that.

🧠 What makes this different

This is not just another CSV viewer.

It’s built specifically for developers who deal with structured data inside CSVs — configs, exports, logs, and hybrid datasets.

✨ Key Features

🏎️ Fast & Scalable

• Handles large CSV files smoothly
• Virtualized table rendering (no UI lag)

🧩 JSON-Aware Cells

• Edit JSON directly inside cells
• Monaco-powered editor for syntax highlighting & validation
• Perfect for config-heavy workflows

✏️ Spreadsheet-like Editing

• Inline editing experience
• Familiar table layout
• Quick navigation across rows & columns

🔄 File Sync & Persistence

• Changes reflect directly in your CSV file
• No manual export/import needed

↩️ Undo / Redo Support

• Safe editing with built-in history tracking

🎯 Who is this for?

This extension is especially useful if you:

• Work with CSV files containing JSON
• Manage config-driven systems
• Handle data exports / logs
• Want to stay inside VS Code instead of switching tools

🧪 Real Use Cases

• Editing feature flags stored in CSV
• Updating API payload configs
• Cleaning and inspecting data exports
• Managing hybrid CSV + JSON datasets

🚀 Getting Started

1. Open any .csv file
2. Launch the editor
3. Start editing — including JSON cells

🔮 What’s coming next

We’re actively improving this tool. Planned enhancements include:

• JSON schema validation per column
• Advanced search (including inside JSON)
• Bulk editing & transformations
• Column typing & validation
• Diff view for CSV changes

💡 Feedback & Contributions

This tool is built for real developer workflows. If you have suggestions, feature requests, or ideas — they’re always welcome.
