How it works
Add your Apache Parquet file. MimiFile checks the format, converts it to JSON, and provides a temporary download when the result is ready.
Convert Parquet to JSON when an API, script, application or human-readable workflow needs JSON records instead of columnar storage.
PARQUET → JSON
Drag and drop, paste a file, or browse your device.
Files are temporary and deleted automatically.
Limits: 50 MB per file · 128 MB total per batch.

Parquet and JSON use different data models. JSON is row-oriented and has a smaller native type vocabulary, so some values require serialized representations.
Current source limit : 50 MB per file. Up to 10 files can be submitted in a batch, subject to the global batch ceiling.
Parquet organizes typed columns for analytics. JSON represents values in objects and arrays, which is easier for many application workflows but physically different.
Check decimals, large integers, timestamps, nulls, binary data and nested fields whenever exact downstream typing matters.
When a tabular destination cannot represent lists or objects directly, nested values are serialized as JSON text where supported instead of being silently discarded.
Nulls and timestamps are preserved when the destination supports them. Binary values can be represented as Base64 text in text-based or spreadsheet outputs.
Check column types, null values, timestamps and nested fields before using the converted file in a production data pipeline.
