Press the shortcut for your target format (e.g., Cmd+Alt+J for JSON).
The content is instantly converted and the editor language is updated.
Parquet Workflow
Exporting to Parquet:
Open a data file (e.g., a large JSON array).
Press Cmd+Alt+P.
Save the file as data.parquet. Schema is inferred automatically.
Importing Parquet:
Open Command Palette (Cmd+Shift+P).
Run Import Parquet to JSON.
Select your .parquet file to load it as JSON.
Beautify (Cmd+Alt+B):
JSON : Validates and re-formats strict JSON.Other Files : Triggers VS Code's standard formatter (supports HTML, CSS, JS, etc.).
Minify (Cmd+Alt+M):
JSON : Removes whitespace.CSS : Removes whitespace and comments.JavaScript : Safe minification via terser (mangles variables, compresses code).
❗ Known Issues
Parquet Schema : Nested objects in Parquet export are currently simplified or stringified. Complex schemas may require manual adjustment.Lossy Conversion : Converting rich formats (like YAML with anchors) to simple formats (like JSON) may lose metadata.
