JSON array to pipe-separated lines
ClientExport JSON object rows as pipe-delimited lines when your scripts or legacy imports expect | separators.
Learn more: JSON pipe export
Join each object row into pipe-delimited text—common in Unix logs, legacy imports, and scripts that use | as a field separator.
Pipe-delimited rows
Pipe separators work well when values rarely contain | characters. They sit between TSV and CSV in the delimiter family—pick the delimiter your downstream script already expects.
Compared to TSV/CSV
If fields include pipes, prefer tab or comma export, or stringify nested objects before export so delimiters stay unambiguous.
Privacy
Export is client-side only.
About JSON array to pipe-separated lines
Pipe-separated export for logs and scripts—local. Parsing and transforms run in your browser—Toolcore does not upload your JSON for this operation.
How to use
Paste a JSON array (or follow the two-array example on join tools). Use Load example when shown, or prefill with ?q= / ?qb= on the tool URL.
Input and limits
Fix JSON syntax errors before expecting output. Very large arrays may slow the tab—trim samples during exploration, then scale up locally.

Common use cases
- Export JSON rows with pipe delimiters for legacy log parsers or Unix-style imports.
- Choose | when commas and tabs both appear frequently in cell values.
- Generate pipe-separated fixtures for scripts that split on |.
Common mistakes to avoid
Pipe characters inside field values
If values contain |, pick tab or comma export, or stringify nested objects first.
Non-array JSON input
Provide an array of object rows for line export.
Expecting CSV quoting rules
Pipe export uses a different delimiter semantics—verify output in your target script.
FAQ
When should I use pipes vs tabs?
Use pipes when your downstream tool already expects |; otherwise TSV is often safer.
Is upload required?
No—export is client-side.
Prefill support?
Yes—?q= and ?qb= for the JSON document.
