Free Online Database & PDF to JSON Converter
DB to JSON is a free online tool that converts SQLite databases (.db, .sqlite, .sqlite3) and PDF documents into clean, structured JSON format. No registration, no downloads, no hidden fees — just upload your file and get instant results. Trusted by developers, data analysts, and researchers worldwide for fast, reliable data conversion.
How to Convert SQLite to JSON Online
Upload your SQLite database file using the drag-and-drop interface or file browser. The tool automatically detects all tables in your database, displays row counts, and lets you select specific tables or export everything at once. The output is pretty-printed JSON with preserved column names as keys. You can copy the result to clipboard or download it as a .json file with one click. Supports .db, .sqlite, and .sqlite3 file extensions with automatic schema detection and column metadata preservation.
How to Convert PDF to JSON Online
Upload any PDF document and the parser will extract text content, detect tabular data, identify key-value pairs, and provide word and character counts per page. The structured JSON output makes it easy to process PDF data programmatically. Supports multi-page PDFs with automatic page detection and content organization. Advanced text extraction methods include stream decompression, BT/ET block parsing, and ASCII fallback for maximum text recovery from any PDF document.
Why Use DB to JSON Converter?
This converter is ideal for developers, data analysts, and anyone who needs to quickly transform database files or PDF documents into JSON format. All processing happens securely on the server — your files are never stored permanently. The tool supports files up to 50MB and includes features like JSON syntax highlighting, line numbers, search within output, copy to clipboard, and one-click download. No software installation required — works directly in your web browser on any device.
Supported File Formats and Features
DB to JSON supports SQLite database files (.db, .sqlite, .sqlite3) and PDF documents (.pdf). For SQLite files, the tool reads the database schema, detects all tables, and exports data with full column metadata including row counts, column names, and data types. For PDF files, it uses advanced text extraction including stream decompression, BT/ET block parsing, and ASCII fallback methods to ensure maximum text recovery from any PDF document. Output includes pretty-printed JSON with syntax highlighting, line numbers, and word wrap toggle.
Privacy, Security, and Data Protection
Your privacy is our priority. Files are processed in memory and immediately deleted after conversion. No data is stored on our servers beyond anonymous conversion statistics. All transfers are encrypted via HTTPS, and the tool implements strict security headers including Content Security Policy (CSP), HSTS, cross-origin protections, and X-Content-Type-Options. No account creation or personal information is required. CSRF protection ensures secure form submissions, and all file uploads are validated for type, size, and content before processing.
Fair Usage Policy and Rate Limiting
DB to JSON is free for everyone with no sign-up required. To ensure fair access, we apply a per-IP quota system of 30 conversions per hour and 100 conversions per day. Quotas reset automatically, and the tool displays your remaining usage in real-time with visual progress meters. This system prevents abuse while keeping the service accessible to all users. Rate limiting is based on your IP address and does not require any account or authentication.
JSON Output Options and Customization
Customize your JSON output with multiple options. Enable pretty-print for human-readable formatted JSON with proper indentation. Include metadata such as row counts, column names, and table information. Toggle word wrap for long lines. Search within the JSON output to find specific keys or values. Copy the entire output to clipboard or download it as a .json file. The tool preserves all data types including strings, numbers, booleans, and null values in the JSON output.
SQLite Database Browser and Table Viewer
Browse your SQLite database structure before converting. The tool displays all available tables with their row counts, letting you choose which tables to export. View column names and data types for each table. Export individual tables or all tables at once. The SQLite viewer supports databases of any size up to 50MB and handles complex schemas with multiple tables, indexes, and relationships. Perfect for developers who need to quickly inspect database contents or export data for analysis.
PDF Text Extraction and Document Parsing
Extract structured data from PDF documents with advanced parsing algorithms. The tool handles multi-page PDFs, detects tabular data using delimiter analysis, identifies key-value pairs via regex pattern matching, and provides detailed word and character counts per page. Supports PDFs with embedded text, scanned documents with OCR-ready output, and complex layouts with multiple columns. The JSON output organizes content by page number with full metadata for easy programmatic processing.
Developer Tools and API Integration
DB to JSON is designed for developers who need quick data conversion without complex setup. The tool works entirely in your web browser — no API keys, no SDKs, no server configuration required. Convert SQLite databases to JSON for use in web applications, mobile apps, data analysis pipelines, or machine learning workflows. The structured JSON output is compatible with all major programming languages including JavaScript, Python, PHP, Ruby, Java, and C#. Use the output directly in your applications or save it for later processing.
