How it works
Add your Apache Parquet file. MimiFile checks the format, converts it to JSON Lines / NDJSON, and provides a temporary download when the result is ready.
Convert Parquet to JSONL when logs, streaming tools or record-by-record pipelines work better with one JSON object per line.
PARQUET → JSONL
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.
Add your Apache Parquet file. MimiFile checks the format, converts it to JSON Lines / NDJSON, and provides a temporary download when the result is ready.
The result changes from typed columnar storage to line-delimited JSON records. JSONL is convenient for streaming, but it does not carry Parquet's schema as a native columnar definition.
Current source limit : 50 MB per file. Up to 10 files can be submitted in a batch, subject to the global batch ceiling.
JSONL can be processed one record at a time and appended easily, which makes it useful for event, log and stream-oriented workflows.
Dates, decimals, binary fields and nested structures can require JSON-compatible representations. Keep the Parquet source when exact schema fidelity 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.
