How it works
Add your Apache Parquet file. MimiFile checks the format, converts it to Excel workbook, and provides a temporary download when the result is ready.
Convert Parquet to XLSX when you need to inspect, filter or share a columnar dataset in an Excel-compatible spreadsheet.
PARQUET → XLSX
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.

A spreadsheet is not a columnar data store. Cell types, worksheet limits and nested-value handling differ from Parquet, so validate large or type-sensitive datasets after conversion.
Current source limit : 50 MB per file. Up to 10 files can be submitted in a batch, subject to the global batch ceiling.
XLSX is convenient for manual review, filtering, formulas and sharing with spreadsheet users who may not have Parquet tooling.
Review row and column counts, date/time values, decimal precision, nested fields, binary data and any columns that exceed normal spreadsheet expectations.
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.
