HOW TO View Large CSV File From A GitHub Repo Without Downloading It Locally

Here are quite a few ways to view large CSVs from a GitHub repo without downloading them locally - 

1) Flat Viewer is a free online viewer for CSV, JSON, and other tabular files stored in public GitHub repos — it displays them in a sortable, filterable table without you having to download them.

The FlatGithub URL format is:

https://flatgithub.com/OWNER/REPO?filename=PATH_TO_FILE

If your file is:

https://github.com/mvark/indiafoodstats/blob/main/Brands/Amul.csv

The FlatGithub link will be:

https://flatgithub.com/mvark/indiafoodstats/blob/main/Brands/Amul.csv

What you can do with Flat Viewer -

  • View the CSV as a table (no GitHub size preview limit)
  • Sort columns
  • Search in the dataset
  • Download the filtered view as CSV or JSON

2) GitHub + Raw + CSV Explorer

Go to your CSV in GitHub

Click Raw

Copy the URL (it will look like https://raw.githubusercontent.com/.../file.csv)

Go to CSV Explorer (requires sign up)

Import the data using Raw CSV file 

3)  Through your own Datasette instance. This will give you SQL search + filters in the browser

4) Using GitHub.dev which is basically VS Code running in your browser. If you need search & filtering inside GitHub.dev, you can install the "Excel Viewer" or "Rainbow CSV" VS Code extensions from the Extensions sidebar — even inside the web version.

If the URL of your CSV file in a GitHub Repo looks like this -https://github.com/mvark/indiafoodstats/blob/main/Brands/Amul.csv

then the link to open it directly in GitHub.dev is this -

https://github.dev/mvark/indiafoodstats/blob/main/Brands/Amul.csv
