How to use TSV to JSON

Copy cells from Excel/Sheets (the clipboard is already TSV) or paste a .tsv file's contents.
Include the header row — it becomes the JSON keys.
Read the JSON array — one object per row, comma-containing values intact.
Cast types downstream where needed — delimiter formats deliver strings.

What is TSV to JSON?

A TSV to JSON converter parses tab-separated rows into an array of JSON objects — header row as keys, each line an object — exactly like its CSV sibling but splitting on tabs. Its killer input is the clipboard: cells copied from Excel or Google Sheets arrive as TSV, so this converter turns a selection copied from any spreadsheet directly into JSON, no export step.

That copy-paste path — select cells, Ctrl+C, paste here, JSON out — is the fastest route from spreadsheet to structured data that exists, and most people don't know the clipboard was TSV all along.

About the TSV to JSON

Paste TSV — a .tsv file's contents or, more often, cells straight from a spreadsheet — and get the JSON array instantly.

Why tabs beat commas as input: no quoting ambiguity. Values containing commas ("1,234.56", "Doe, Jane") pass through untouched, so data that would need careful CSV quoting just works. The workflow it enables: a teammate's spreadsheet open in one tab, select the range, copy, paste here, and the JSON drops into your seed file, API call or config — five seconds, no export dialogs, no encoding surprises.

Same caveats as all delimiter formats: values arrive as strings (cast numbers where types matter), header texts become keys verbatim, and literal tabs inside values — rare — are the one thing the format can't express. For comma-delimited files, the CSV to JSON converter is the sibling.

Frequently Asked Questions

Yes — spreadsheet copy puts tab-separated text on the clipboard, which is exactly TSV. Select the range (headers included), copy, paste here: the fastest spreadsheet-to-JSON path there is.

Whenever values contain commas — prose, names ("Doe, Jane"), formatted numbers ("1,234.56"). TSV needs no quoting for them, so nothing can mis-split. And whenever the source is a clipboard copy, which is TSV by nature.

First line becomes the keys for every object. "Product Name" in the header yields "Product Name" keys — tidy headers before converting if the JSON feeds code.

They arrive as strings — TSV carries no types. Cast in consuming code where it matters; it's the standard caveat of every delimiter format, not a TSV quirk.

Literal tab characters inside a value — they'd split the field. Real data almost never contains them; if yours does, quote-wrapped CSV is the fallback.
