Paste your CSV data or drag CSV files here
Upload CSV files or directly paste CSV data. The tool intelligently recognizes various delimiters (comma, tab, semicolon, pipe, etc.), automatically detects data types and encoding formats, supporting fast parsing of large files and complex data structures.
Edit data using our professional online table editor. Supports deleting empty row data, removing duplicate rows, transposing data, sorting by rows, regex find & replace, and real-time preview. All changes will automatically convert to Protocol Buffers format with simple and efficient operation and precise reliable results.
Generate standard Protocol Buffer definitions with support for message types, field options, and service definitions. Generated .proto files can be compiled for multiple programming languages.
Note: Our online conversion tool uses advanced data processing technology, runs completely in the browser, ensures data security and privacy, and does not store any user data.
CSV (Comma-Separated Values) is the most widely used data exchange format, perfectly supported by Excel, Google Sheets, database systems, and various data analysis tools. Its simple structure and strong compatibility make it the standard format for data migration, batch import/export, and cross-platform data exchange, widely used in business analysis, data science, and system integration.
Protocol Buffers (protobuf) is Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data. Widely used in microservices, API development, and data storage. Its efficient binary format and strong typing make it ideal for high-performance applications and cross-language communication.
