Extract text from Newline Delimited JSON files (NDJSON)
To convert NDJSON JSON files to another format, you need jq or other Data software.
To convert other file formats to the "Newline Delimited Data Format" file type, you need software like jq or a similar tool.
The .ndjson (Newline Delimited JSON) format stores structured data where each line is an individual, valid JSON object, separated by newline characters. It is primarily used for streaming data, continuous structured logging, and bulk data processing. A notable consumer use case is the Apple App Privacy Report on iOS, which exports network activity logs in the .ndjson format.
While highly efficient for machine parsing and streaming large datasets without loading everything into memory, .ndjson files present significant usability challenges. Standard text editors freeze when opening massive log files. More importantly, standard JSON parsers will throw a syntax error if you try to read an .ndjson file, because they expect a single root array or object, not multiple independent objects. Furthermore, everyday data tools like Microsoft Excel or Google Sheets cannot natively open or parse .ndjson files, making basic data analysis extremely frustrating for non-developers.
To make this data readable or analyzable, you must convert it. For data analysis and pivot tables, convert .ndjson to CSV. To use the data in standard web APIs, convert it to a standard JSON array. For simple text review or archiving, convert to TXT.
Convert.Guru analyzes your NDJSON file, detects the exact format, and lets you read the text inside.
Users also converted JSON, TXT, CSV, ZIP, LOG, XLSX, GZ, JSONL, POD, SYNCED, SLDPRT, RTF and ACSM files.
If you want to convert NDJSON file to JSON, CSV, HTML, HTM, CSS, JS, PHP, ASP, ASPX, JSP, JSPX or PY, you can use jq or similar software from the "Streaming Structured Data Logging" category. In the File menu, look for Save As… or Export….
To convert RSS, CSS, CGI, SITEMAP, PL, WEBMANIFEST, JSON, JS, XML, HTML, ICO or HTM files to NDJSON, try jq or another comparable tool in the "Streaming Structured Data Logging" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NDJSON converter.
