How are columns chosen for the TSV output?

The converter collects every unique key across all objects in the array. Objects with missing keys produce empty cells for that column.

Does it support nested JSON?

Nested objects and arrays inside values are serialized as JSON text within their cell, so no data is lost.

Why use TSV instead of CSV?

TSV avoids delimiter conflicts when your data contains commas, which is common in addresses, descriptions and lists.

How do I use JSON to TSV Converter?

Paste your JSON array into the input box.
Columns are detected from your object keys instantly.
Copy the TSV or download it as a .tsv file.

Why use our json to tsv converter?

This converter reads JSON arrays of objects, collects the union of all keys as columns and writes each object as a tab-separated row. Because output uses tabs, values containing commas never corrupt the table structure. It is the fastest path from an API response to a paste-ready spreadsheet row set, and it runs entirely on your device.

JSON vs TSV — converting an array to a table

A JSON array of flat objects maps cleanly to a tab-delimited table. This conversion is ideal for feeding JSON data into statistical or spreadsheet tooling that expects rectangular input.

Aspect	JSON source	TSV output
Shape	Array of objects with repeated keys	Header row plus one line per object
Keys	Repeated in every element	Written once in the header
Nesting	Nested values must be flattened	Only scalar cells can be represented
Size	Verbose	Compact
Best for	Web APIs and code	R, pandas, and spreadsheet analysis

From a JSON array straight into a tab-separated file

Some bioinformatics, statistics and data-science toolchains expect TSV. Converting a JSON array this way keeps row/column alignment while using tab separators.

Input JSON array

[
  { "gene": "TP53", "samples": 214 },
  { "gene": "BRCA1", "samples": 98 }
]

Converted TSV

gene	samples
TP53	214
BRCA1	98

Paste a JSON array and get a TSV ready for R, statistical pipelines, or a bulk import that expects tab-separated values.
