xmetric vs Looker Studio for a CSV or Parquet file

Your situation: you have a CSV or Parquet file and want a chart, without pasting it into Google Sheets or uploading it to Google first.

Data Studio, the new name for Looker Studio, doesn't need Google Sheets for a CSV: its Upload CSV files connector takes the file directly. But the file is stored in Google Cloud, each dataset is capped at 100MB, and Parquet isn't among its file connectors. If the file shouldn't leave your computer, or you just want a chart now, drop the CSV below: xmetric reads every row in this browser (the CSV chart accepts up to 160 MiB and 3.5 million rows, or 32 MiB on low-memory or unknown-memory devices) and draws a first chart. Parquet opens in the xmetric app, which is in development.

Where Data Studio is the better choice

Where xmetric fits

Getting a CSV into Data Studio without Google Sheets

Pick the Upload CSV files connector and add the file; no spreadsheet is involved. Before you use it with work data, know three things from Google's documentation: the file is stored in Google Cloud Storage, each dataset can be at most 100MB (2GB per user in total), and the datasets you create can't be shared source. Uploading itself is free.

And Parquet?

Data Studio's documentation lists Upload CSV files, Microsoft Excel and Extract data as its file connectors, alongside Google Sheets; Parquet isn't one of them source. The usual route is to load the file into a database Data Studio connects to, such as BigQuery. xmetric's app will open a Parquet file in the browser without loading it anywhere. It's in development, so today save the data as CSV and use the box above.

It was called Looker Studio until April 2026

Google renamed Looker Studio back to Data Studio (announced April 11, 2026). source Older guides and forum answers still use the Looker Studio name.
