If you have JSON sitting in a file or an API response and you need it as rows and columns, this is the page for you. The JSON to CSV tool takes a JSON array and hands back a CSV you can drop straight into a spreadsheet. You can convert json to csv online in a couple of seconds, and because it runs in your browser, the data never goes anywhere.
The short version.
JSON is great for code and APIs. Spreadsheets do not read it well. This tool bridges that gap: paste a JSON array of objects and it reads the keys, lines them up as columns, and writes one row per object. To convert json into csv you press a single button.
Under the hood it uses Papaparse, the same library plenty of production apps rely on, so commas, quotes, and line breaks inside your values are handled correctly. As a plain csv converter it sticks to standard quoting, which means the file opens cleanly wherever you take it next.
This is what most people are really after.
Nine times out of ten, the reason someone wants CSV is to get JSON into a spreadsheet. The output works as a json to excel converter without any extra step: convert the JSON, save the file, and open csv file online in Google Sheets or open json file in excel on your desktop.
If your search was json to excel online or convert json to excel online, the CSV route is the one that keeps your columns lined up. There is no separate upload, and json to excel online really does come down to these two clicks.
Three steps, then you are done.
The flow is the same whether you have ten rows or ten thousand. This online json to csv converter does the parsing; you just paste and copy.
Small options that matter once you export.
By default the output is comma separated, which is what almost every app expects. If you were looking for a comma separator online, or you need tabs or semicolons instead, switch the delimiter when you import the file into your spreadsheet. As a general csv file converter it does not lock you into one format, so it behaves the same whether you treat it as a file to csv converter for a single record or a long export.
There is no built in csv to pdf converter, but getting to PDF is easy once you have the CSV. Open the file in Excel or Sheets, then use Print or Export to PDF. Two steps, no extra tool.
JSON to CSV is one of a small family.
Sometimes you need the reverse. The CSV to JSON tool handles csv to json when you want to pull a spreadsheet back into structured data. For other shapes, the JSON to XML tool is a json to xml converter online with attributes preserved, and the XML to JSON tool works as an xml to json converter online in the other direction.
The CSV you get here is plain text, so it doubles as a json to text converter for quick exports. Since your JSON is already a json to array online structure, each object simply lands on its own row. For html to json there is no direct converter yet, so the usual move is to pull the values you need into a JSON array first, then run that through this page.
Good input, good output.
If your JSON will not convert, it is almost always a formatting problem. For json escape online or json decode online work, run it through the JSON Formatter first; it tidies and validates the structure so it parses here. That same tool acts as a string to json converter online when you paste raw text that needs wrapping into proper JSON.
One thing to know: this is not a json schema converter and not a json schema to json converter. It expects real data, not a schema definition. If you are validating against a schema, do that in the JSON Validator before you convert.
When you do not have clean JSON yet.
If you are still assembling your data, a json converter online gets you to valid JSON before the CSV step. People look for a json convertor in a dozen different ways, but the goal is the same: a clean array you can convert to json file output and then turn into rows. Once you have that, this page handles the CSV side in one click.
