Enter a web page URL containing table data to automatically extract structured data
Paste your JSON Array data or drag JSON files here
Upload JSON files or paste JSON arrays. Supports automatic recognition and parsing of object arrays, nested structures, and complex data types. The tool intelligently validates JSON syntax and provides error prompts.
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.
JSON (JavaScript Object Notation) is the standard table data format for modern web applications, REST APIs, and microservice architectures. Its clear structure and efficient parsing make it widely used in front-end and back-end data interaction, configuration file storage, and NoSQL databases. Supports nested objects, array structures, and multiple data types, making it indispensable table data for modern software development.
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.
