Rawsort is a suite of web-based data processing utilities designed for individuals and organizations that prioritize data privacy. By performing all file operations locally within the user's web browser, Rawsort ensures that sensitive data, including financial exports from platforms like Stripe or Shopify, never leaves the device or is transmitted to a third-party server. The tool is developed as a privacy-first alternative to cloud-based SaaS tools, allowing users to analyze, convert, and visualize data without needing to create an account or provide any personal information.

The functionality of Rawsort spans eight distinct engines, ranging from specialized data analyzers to file conversion utilities. The platform parses uploaded files using native browser APIs, enabling instant visualization and insight generation. Whether working with CSV, JSON, or Excel (.xlsx) files, users can generate performance charts, detect patterns, identify anomalies, and create standardized reports that are ready to be shared with investors or team members. All tools operate entirely offline once the initial page has loaded, making them suitable for secure environments or offline work.

Some of the key features are:

• CSV Analyzer: Provides automated trend detection, anomaly alerts, and summary charts for large CSV files.
• JSON Analyzer: Offers a tree-view structure, visual charts, and data insights for API payloads and nested JSON objects.
• Excel Engine: Reads multi-sheet Excel workbooks and extracts key numeric insights without needing external spreadsheet software.
• Data Converters: Supports seamless conversion between CSV and JSON formats while preserving data types and structure.
• CSV Merger: Allows users to combine multiple CSV files with smart column alignment and source tracking capabilities.
• Founder Update Templates: Generates professional, copy-ready investor updates in formats like YC-style or Sequoia memo based on uploaded data.
• Timeline Tracker: Enables local tracking of KPI snapshots over time for period-over-period comparison without cloud storage.
• Privacy-First Architecture: Guarantees that no data is ever uploaded or transmitted, as all processing is client-side.

Rawsort operates through a simple interface where users drag and drop their files directly into the browser tab. The platform automatically detects file schemas, parses numeric fields, and calculates a business health score based on metrics such as growth trends, consistency, and momentum. The results are presented in real-time, allowing users to interact with their data, toggle between different visualization types, and export cleaned data or reports as needed. Since it utilizes the browser's local storage for features like the Timeline Tracker, users can maintain a long-term record of their business metrics while keeping total ownership of the information.

Some common use cases include:

• Analyzing Financial Exports: Securely reviewing Stripe, Shopify, or bank CSV exports for revenue and churn trends without uploading them to a cloud-based dashboard.
• Preparing Investor Updates: Quickly converting internal spreadsheet data into professional, YC-style investor communication templates.
• API Data Visualization: Pasting raw JSON API responses to visualize the structure and key signals within the data.
• Database Analysis: Inspecting SQL dumps or export files from local databases for anomalies and patterns before importing them elsewhere.
• Offline Data Processing: Working with sensitive or confidential spreadsheet data while disconnected from the internet during travel or in secure work environments.
• Comparative Reporting: Using the Timeline Tracker to compare two different periods of business data side-by-side to visualize progress and delta.
