Analyze CSV Files
Without Uploading
Anything
Rawsort processes your CSV entirely in your browser. No file is ever sent to a server. No account needed. Just drop your file and get instant charts, column stats, trend detection, and a copy-ready report — completely privately.
Open the CSV Analyzer
Drop any CSV file. It stays in your browser the entire time. Nothing is uploaded. Works with Stripe, Shopify, database exports, or any spreadsheet data.
Open the CSV Analyzer
Click the button above to go to the Rawsort CSV Analyzer. No account, no signup, no installation needed.
Drop or paste your CSV
Drag your .csv file onto the upload area, or click to browse. The file is read directly in your browser using the FileReader API.
Get instant private analysis
Charts, column stats, trend detection, anomaly alerts, and a copy-ready report — all generated locally. Close the tab and the data is gone.
Zero upload, zero risk
Your CSV file never leaves your device. Rawsort uses browser-native JavaScript to read and analyze the file entirely locally. No server, no storage, no third parties.
Instant analysis in seconds
Drop a CSV and get charts and insights in under a second. Works with files up to thousands of rows. No loading spinner, no waiting for a server to respond.
Data disappears when you close the tab
Rawsort holds your data in browser memory only. Close the tab and everything is gone. No cookies, no localStorage persistence of your file data.
Is it really possible to analyze a CSV without uploading it?
Yes. Rawsort uses your browser's built-in JavaScript engine to process CSV files entirely on your device. The file is never sent to any server.
Why should I avoid uploading CSV files to online tools?
CSV files often contain sensitive data — revenue figures, customer emails, or internal metrics. Uploading them to third-party servers means that data could be stored, sold, or exposed in a breach.
What kinds of CSV files can I analyze without uploading?
Any CSV file works — Stripe exports, Shopify orders, database dumps, analytics exports. If it's a .csv file, Rawsort can analyze it locally.
Does Rawsort work offline?
Once the page has loaded, Rawsort works fully offline. The analysis runs in your browser and requires no internet connection after the initial page load.
