Frequently Asked Questions

What is the difference between Parquet and JSON?

Parquet is a columnar storage format optimized for analytics and large datasets. JSON (JavaScript Object Notation) is a hierarchical format perfect for web APIs, NoSQL databases, and modern applications. Convert Parquet to JSON when your data needs to integrate with web services or JavaScript applications.

Can I convert large Parquet files (10M+ rows) to JSON?

Yes! Diwadi can handle Parquet files with 10 million, 50 million, or even billions of rows. The conversion streams data efficiently so you won't run out of memory, unlike browser-based tools that crash on large files.

Will the conversion preserve my data types?

Yes! Diwadi preserves all Parquet data types including integers, floats, strings, booleans, dates, and nested structures. Complex types are converted to their JSON equivalents correctly.

Can I batch convert multiple Parquet files to JSON?

Absolutely! Select entire folders and convert hundreds or thousands of Parquet files to JSON in one operation. Much faster than online tools that require individual file uploads.

What JSON output formats are supported?

Diwadi outputs standard JSON arrays of objects, where each row becomes an object with column names as keys. The output is properly formatted and can be used directly in APIs, databases, or applications.

Why use desktop converter vs online tools?

Desktop conversion is instant (no upload wait), handles unlimited file sizes, works offline, and keeps your data 100% private. Online tools require uploading sensitive data, have file size limits (usually 10MB), and are slower for large files.

Is Parquet to JSON conversion free?

Completely free with unlimited conversions. No file size limits, no watermarks, no trials, no credit card required.

Can I convert JSON back to Parquet?

Yes! Diwadi supports bidirectional conversion - Parquet to JSON and JSON to Parquet. Perfect for data interchange between analytics systems and web applications.
