Extract text from JSON Lines files (JSONL)
To convert JSONL files to another format, you need jq or other Data software.
To convert other file formats to the "Line-delimited JSON format" file type, you need software like jq or a similar tool.
The .JSONL file extension represents a JSON Lines data file. In this format, each line of text is a completely independent, structurally valid JSON object. This append-only structure is heavily utilized for processing massive data streams, system logs, and machine learning training datasets because it allows applications to process data row-by-row without loading the entire file into memory.
Despite its technical efficiency, .JSONL is a highly inconvenient format for end-users. Large .JSONL files will crash standard text editors, and they completely lack the formatted 'pretty-printing' that makes standard JSON readable. Furthermore, everyday spreadsheet applications like Microsoft Excel cannot parse .JSONL data, leaving you unable to sort, filter, or analyze the information. This becomes a severe problem when companies export your personal data - such as Google Nest user telemetry - in this format, essentially locking non-technical users out of their own information.
To make this data usable, you must convert it. For data analysis, viewing, and editing, convert your .JSONL file to CSV or XLSX to flatten the records into a readable, tabular spreadsheet. If you need to submit the data to a standard web API or application, convert it to standard JSON to wrap the lines into a proper array.

Convert.Guru analyzes your JSONL file, detects the exact format, and lets you read the text inside.
Users also converted JSON, FAA, FNA, NDJSON, FASTA, PDF, ZIP, FMF, TST and KDT files.
If you want to convert JSONL file to JSON, HTML, HTM, CSS, JS, PHP, ASP, ASPX, JSP, JSPX, PY or RB, you can use jq or similar software from the "Streaming Data Storage" 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 JSONL, try jq or another comparable tool in the "Streaming Data Storage" 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 JSONL converter.
