Convert between JSON, XML, CSV, and YAML in any direction. RFC-4180 CSV parsing, YAML round-trip, copy or download - runs entirely in your browser.

Who Uses Data Converter - JSON / XML / CSV / YAML

Data Converter is the go-to for backend developers translating between formats during integration work - JSON request bodies to XML for a legacy SOAP partner, YAML Helm / Kubernetes manifests to JSON for a CI script, CSV vendor feeds to JSON for an ETL pipeline, or YAML config to CSV for a stakeholder review. Indian dev teams use it heavily for converting GST invoice CSVs to JSON for ERP imports, translating bank statement exports, and reshaping HR data between formats. Because everything runs in the browser, sensitive payloads (API tokens, customer rows, regulated records) never touch a server.

Frequently Asked Questions

Is the Data Converter really free?

Yes. JSON ↔ XML ↔ CSV ↔ YAML in every direction is free - no signup, no API key, no row caps. The only practical limit is what your browser can hold in memory.

Does my data leave my device?

No. Parsing and conversion run via JavaScript in your browser. Your payloads - including production exports, customer data, or API tokens - never touch any CleverTools server.

Which directions are supported?

All twelve. Any format → any other format: JSON ↔ XML ↔ CSV ↔ YAML in any combination. Internally the converter pivots through JSON, so a CSV → YAML conversion is just CSV → JSON → YAML stitched together.

Will it handle CSV with quoted commas, escaped quotes, and multi-line cells?

Yes. CSV parsing uses PapaParse, which is RFC-4180 compliant - it correctly interprets quoted fields, commas inside quotes, escaped double-quotes, and embedded newlines inside cells.

How is YAML handled?

YAML uses a built-in parser that supports nested objects, arrays, scalar types (strings, numbers, booleans, null), and standard 2-space indentation. Block scalars (| and >) are detected; for advanced YAML features (anchors, multi-doc), prefer the JSON pivot first.

Can it convert XML SOAP responses to JSON?

Yes - paste the SOAP XML body, pick XML as input and JSON as output. The reader uses the browser's DOMParser: it takes <item> elements as records, or the root element's children if there are none. Attributes are not read.

What's the largest payload it can handle?

Limited only by your device's memory. If the page slows down, split the file or reduce the payload.

Why does my CSV-to-JSON output have all-string values?

The Data Converter preserves CSV cells as strings to avoid silent precision loss on long numeric IDs (Aadhaar, mobile, GSTIN). For typed conversion (numbers, booleans, nulls), use the dedicated CSV to JSON tool which has an explicit type-inference toggle.

Guide

How to use this data converter

Every conversion goes through JSON: your input is read into JSON first, then written out in the format you picked.

Twelve format pairs, one pivot

1
Choose From and To
Tap the format you have under From and the one you need under To.
2
Paste the data
Half-typed input is ignored while you type, so you never see a flood of errors.
3
Check for errors
If nothing appears, tap Convert now. It shows exactly what the parser did not like.
4
Swap to go back
Swap moves the output into the input and flips the formats, ready to convert back.

Guide

Habits for clean conversions

Each format has one habit that avoids most surprises.

JSON

Start with an array

CSV and XML are lists of records, so an array of objects converts most cleanly.

One object per record
Same keys in each
Nested values allowed

CSV

Keep one header row

The first row names the keys. Every value comes out as text, so check numbers afterwards.

Unique column names
Quote cells with commas
No title rows

XML

Use child elements

The reader takes child elements and their text. Attributes are not read.

<name>Asha</name>
Not name="Asha"
One root element

YAML

Indent with spaces

YAML forbids tabs for indentation. Two spaces per level is the common choice.

No tabs
Consistent depth
Quote text like yes or 007

Formats

The four formats, side by side

What each one is good at, and what the converter does with it.

JSON

Typed and nested

Objects, arrays, strings, numbers, true, false and null. The pivot every conversion goes through.

APIs and config
Types kept
Any depth

XML

Tags and a root

Output wraps each record in <item> inside one <root>, with keys made into safe element names.

SOAP and feeds
Escapes & and <
Repeated tags become arrays

CSV

A flat table

Rows and columns of text. Nested values are written into their cell as JSON text.

Spreadsheets
Union of all keys
Missing keys left blank

YAML

Readable config

Indentation shows nesting. Output quotes every string so values like true or 123 stay text.

Kubernetes, CI files
Comments with #
Round-trips to JSON

Guide

Who moves data between formats

Different tools speak different formats. These jobs sit in between.

Backend developers

Integrations

An old partner sends XML, the new service wants JSON, and the ops team wants a spreadsheet.

Good habit: convert to JSON first · check types · then write out

DevOps engineers

Config

Config moves between JSON and YAML files for different tools and pipelines.

Good habit: JSON to YAML · indent with spaces · review the diff

QA and testers

Fixtures

Test data lives in a spreadsheet, but the test runner wants JSON or YAML.

Good habit: CSV to JSON · fix number types · commit the fixture

Data analysts

Exports

API exports arrive as JSON or XML, and Excel wants CSV.

Good habit: JSON to CSV · check nested cells · open in Excel

The standards

What each standard requires

The rules the converter follows when it reads and writes each format.

XML 1.0

From the W3C XML 1.0 recommendation.

Exactly one root element
Names can't start with a digit
Names starting with xml are reserved
& and < must be escaped
Every tag must close

YAML 1.2

From the YAML 1.2.2 specification.

Designed as a superset of JSON
No tabs for indentation
Comments start with #
Indentation shows nesting

Not handled

Things the converter does not read. Convert these with a full library.

XML attributes
YAML anchors and aliases
YAML tags
Several YAML documents in one file

Guide

Keeping conversions predictable

A few habits make the same data convert the same way every time.

1
Pick one source of truth
Edit the data in one format and convert from it, rather than editing two copies.
2
Round-trip to check
Convert to the target, swap, and convert back. Anything that changed did not survive the trip.
3
Watch number types
CSV and XML carry text only. Numbers read from them arrive as strings in JSON.
4
Keep keys simple
Letters, digits and underscores survive every format. Spaces and symbols get renamed in XML.

Pro tips

Pro tips for format conversion

Small habits that save time on every payload.

Swap to reverse

Swap moves the output into the input, so you can check a round trip in one tap.

Convert now shows errors

Errors stay quiet while you type. Tap Convert now to see the parser's message.

CSV values are text

CSV to JSON keeps every value as a string, exactly as written in the file.

Nested data in CSV

Objects and arrays are written into one cell as JSON text, so nothing is lost.

Records as <item>

XML input with <item> elements uses them as records. Otherwise the root's children are used.

Strings stay strings

YAML output quotes every string, so "true" and "007" never turn into other types.

Odd keys renamed

In XML, a key like "first name" becomes first_name, and "2024" becomes _2024.

Private by design

Tokens and customer records are parsed in this tab and never uploaded.

Pro tip: only JSON and YAML carry types

CSV cells and XML text are always text. When you convert them to JSON, numbers arrive as strings like "31". Convert JSON or YAML to each other and the types survive.

Formats

JSON or YAML? Which one to use

Both hold the same nested data. They differ in who reads them most.

For programs

{}braces and quotes

JSON

Strict and simple: every parser reads it the same way. No comments, so it suits data sent between programs.

Best for APIs, logs and data exchange

For people

#comments allowed

YAML

Indentation instead of braces, and comments with #. Easier to read and edit by hand, so it suits config files.

Best for config, CI and deployment files

Sending to an APIJSON.

Config people editYAML, with comments.

Opening in ExcelCSV.

Same dataJSON and YAML round-trip.

Verdict: use JSON for data programs exchange and YAML for files people edit. The studio above converts between them without losing types.
