Drop XLSX (Excel) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. There is nothing else to set. The work happens in this tab.
Save the result. When one file produces several NDJSON files they come as a single ZIP.
The XLSX to NDJSON converter is part of this page and runs inside your browser. Your spreadsheets are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
XLSX is awkward for scripts, databases and import tools that expect plain text. NDJSON can be streamed and appended to one record at a time. XLSX is at home in spreadsheets with formulas, formatting and several sheets; NDJSON is the usual choice for logs and large record streams that are processed line by line.
One XLSX can produce several NDJSON files (one record per line); when it does, they are offered together as a ZIP download.
Each record is written on its own line with no enclosing array. A workbook or database with several tables gives one file per table.
XLSX is Excel's format since Office 2007. A workbook can hold many sheets with formulas, formatting and charts. Programs and scripts usually prefer the same data as CSV or JSON.

XLSX converterNDJSON writes one complete JSON value per line, with no enclosing array or commas between records. A program can read, append or process it one line at a time without loading the whole file, which makes it popular for logs, exports and data loading. JSON Lines (.jsonl) is the same format under another name.

No. The XLSX to NDJSON conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
The values are kept. Anything NDJSON has no way to express, such as formatting, formulas or nesting, is simplified or left out.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the XLSX file, press Convert and save the NDJSON. There is nothing to install.
Yes. Spreadsheet files up to 150 MB are accepted; a larger file is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
