## Most critical reviews (6 lowest-rated)

### 1/5 — Can’t open local parquet files

*2026-07-03*

I was hoping things had improved, but it seems not. Opened the app, dropped a .parquet file where it said, got 3 alerts about a duckdb plugin which I accepted, then the viewer window opened with an “Unable to open this Parquet data” error.

### 1/5 — DELETE ME

*2026-03-12*

This thing needs to be deleted off the store

### 1/5 — Simply does not work

*2025-02-03*

It does not work for parquet files with 16 records and not record. I tested with a very simple schema

### 1/5 — Unusable

*2023-07-12*

Seems hastily put together. Cant open multiple files. UI is pretty but unintuitive. Most every feature is hidden in the pay-wall. Terrible all around.

### 1/5 — Can't open parquet files written by pyarrow

*2023-04-04*

I can't get this app to work. It won't open parquet files written by pandas --> pyarrow --> parquet.

There also seems to be some sort of subscription model which isn't obvious from the app store.

### 1/5 — Virtually unusable without purchasing credits to run queries

*2023-01-15*

This has to be a joke. The screenshots don't show this, but you have to buy credits/subscription to run queries. If you don't pay, you can only page through your file and 100 records at a time. Given that the parquet format is specifically used for large volumes of data, it renders the free version of the app useless.
