Why Bulk Conversion?

When working with multiple JSON files — whether from API exports, database dumps, or configuration sets — converting them one by one is tedious and time-consuming. Bulk conversion lets you process dozens or hundreds of files in a single operation, saving significant time.

Supported Output Formats

Formatted JSON — Pretty-print all files with consistent 2-space indentation
Minified JSON — Compress all files by removing whitespace (reduces file size)
CSV — Convert JSON arrays to comma-separated values for spreadsheets
YAML — Transform to YAML for Kubernetes, Docker, and CI/CD configs
XML — Convert to XML for legacy systems and SOAP integrations
TypeScript — Generate TypeScript interfaces from each JSON structure

How the ZIP Download Works

After processing, all converted files are packaged into a single ZIP archive for convenient download. Each file retains its original name with the appropriate new extension (e.g., data.json becomes data.csv). The ZIP is generated entirely in your browser using JSZip — no server involved.
