Stop downloading a 2 GB log file to read 20 lines
Cloud File Viewer previews CSV, JSON, text, log and gzip files directly in the Google Cloud Storage browser. Only the chunk you are reading is fetched. Nothing is downloaded, and nothing leaves your machine.
Built for people who live in GCS buckets
Data engineers, developers and cloud operators who open the same Storage browser twenty times a day.
Preview without downloading
A magnifier appears next to every supported file in the Storage browser. Click it and the content opens in place. It reads CSV, JSON, plain text, logs and gzip archives.
Search inside large files
Look for a term across a file far too big to open. Results stream in page by page with a line count and a timer, and you can stop the search at any point.
Only fetches what you read
Files are read in chunks using HTTP range requests. Opening the first page of a 2 GB log costs you one megabyte, not two gigabytes.
Works on your private buckets
It uses the Google session you already have in the browser. No API key to paste, no service account to create, no extra permission to grant.
Your recent buckets, one click away
The popup keeps the buckets you actually use, so you stop navigating the Storage browser from the top every single time.
Nothing leaves your device
No account, no server, no analytics. Bucket names, file paths and usage stats stay in your browser's local storage and are never sent anywhere.
Three steps, no setup
No API key, no service account, no configuration file.
Install the extension
One click from the Chrome Web Store. Nothing to configure afterwards.
Open a bucket in the Cloud Console
Go to Cloud Storage as usual. A magnifier appears next to every file the extension can read.
Click the magnifier
The file opens in a panel. Page through it, or switch to the Search tab to look for a term inside it.
Questions
Everything you need to know.
Yes. It reads files through the Google session already open in your browser, with exactly the permissions your account has. If you can open the file in the Cloud Console, the extension can preview it.
CSV, JSON, plain text, log files and gzip archives. Parquet and Avro are not supported yet. If that is what you need, say so at contact@mlidevstudio.com. It is the most requested feature and the next one being considered.
No. There is no server and no account behind this extension. File content is fetched by your browser straight from Google Cloud Storage and displayed locally. Bucket names, file paths and usage statistics are kept in your browser's local storage and never sent anywhere.
It never loads the whole file. Content is fetched one chunk at a time with HTTP range requests, and you page through it. Search works the same way, streaming results as it scans.
Nothing. It is free, with no account and no paid tier at the moment.
Not today. It is built specifically for the Google Cloud Storage browser. S3 and Azure Blob are not supported.
Add it and forget it
It sits quietly in the Cloud Console until you need to look inside a file.
