About NDJSON files
The .NDJSON (Newline Delimited JSON) format is a text-based standard for storing structured data, where each line represents a distinct, valid JSON object. Unlike standard JSON files that require the entire dataset to be wrapped in brackets [] and separated by commas, .NDJSON allows for efficient line-by-line processing. This makes it the format of choice for server logs, high-throughput API streams, and large data exports - most notably, Apple uses it for their App Privacy Reports.
However, this efficiency is a common issue for standard workflows. Most conventional JSON parsers will reject an .NDJSON file as invalid syntax because it lacks a root element. Furthermore, trying to open these files in Microsoft Excel usually results in all data being dumped into a single column, making analysis impossible without complex Power Query import steps. To make this data usable, users typically need to convert .NDJSON to CSV for spreadsheet analysis, standard JSON arrays for web compatibility, or XML for legacy enterprise systems.
Convert.Guru analyzes your NDJSON file, detects the exact format, and lets you read the text inside.
If you want to convert NDJSON file to JSON, CSV, HTML, HTM, CSS, JS, PHP, ASP, ASPX, JSP, JSPX or PY, you can use Visual Studio Code or similar software from the "Structured Data Streaming" 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 Visual Studio Code or another comparable tool in the "Structured Data Streaming" category.
The NDJSON Converter Story
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.
