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 JSONLines Format format with simple and efficient operation and precise reliable results.
Generate standard JSONLines format with each line outputting a complete JSON object. Suitable for streaming processing, batch import, and big data analysis scenarios, supporting data validation and format optimization.
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.
JSON Lines (also known as NDJSON) is an important format for big data processing and streaming data transmission, with each line containing an independent JSON object. Widely used in log analysis, data stream processing, machine learning, and distributed systems. Supports incremental processing and parallel computing, making it the ideal choice for handling large-scale structured data.
