How do I convert JSON to TSV?

Add your JSON file to the upload area above, then press Convert. The TSV file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to TSV reduce quality?

The result is a reconstruction rather than a perfect copy. It is genuinely useful for reading and reuse, but review it before relying on it for anything important.

How large a file can I convert?

Up to 100 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

JSON to TSV Converter

Turn JSON files into TSV in a couple of clicks. The default data interchange format for APIs. Like CSV but tab-delimited — safer for text with commas. The result is a best-effort reconstruction; check it before relying on it.

JSON and TSV explained

JSON represents structured data as nested objects and arrays. It came from JavaScript but is now the default interchange format for essentially every web API.

TSV is CSV with tab characters as separators. Because tabs almost never appear inside data fields, it sidesteps most of CSV's quoting problems.

Where JSON files come from: APIs, configuration files and application data exports.
Where TSV is used: Bioinformatics, data pipelines and anywhere fields contain commas.

JSON vs TSV

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

JSON compared with TSV
Property	Source	Target
Compression	None	None
Introduced	2001	—
Browser support	Every modern language and tool.	Wide, especially in data tooling.

JSON is stronger at: Native support in every modern language. Handles arbitrary nesting. Distinguishes strings, numbers, booleans and null.
TSV is stronger at: No ambiguity with commas inside values. Simpler parsing than CSV. Common in scientific data.

Why convert JSON to TSV?

People make this switch when they run into the limits of JSON: large flat tables, where CSV is smaller and simpler. TSV is the better fit when your data contains commas and you control both ends of the pipeline.

JSON limitations that prompt the switch: No comments allowed. Verbose for large tabular datasets. No date type, so dates are strings by convention.
What you give up: Tabs are invisible, making manual editing error-prone. Less universally recognised than CSV.

What is preserved when converting JSON to TSV?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.

About these formats

Source

JavaScript Object Notation

The default data interchange format for APIs.

Extensions: .json
MIME type: application/json
Best for: APIs · Configuration · Structured records
Compatibility: Every modern language and tool.

Target

Tab-Separated Values

Like CSV but tab-delimited — safer for text with commas.

Extensions: .tsv, .tab
MIME type: text/tab-separated-values
Best for: Data pipelines · Text containing commas
Compatibility: Wide, especially in data tooling.

Nested structures are flattened into dotted column names (user.address.city). Deeply irregular data may produce a sparse table — check the result before relying on it.
