A free, in-browser JSON to CSV converter.

JSON to CSV Converter

A simple JSON to CSV converter that handles objects and nested documents.

Conversion happens inside the browser, in straight JavaScript. It may choke on large files.

Please file all bugs in the issue tracker.

Read more about the converter and why I built it: "Making JSON as simple as a spreadsheet".

json's Issues

Streaming JSON parser?

If it's coming from a URL, can we do streaming JSON in-browser? @maxogden sez:

JSONStream is good but not perfect (has memory leaks iirc). More recently there's a library called oboe.js that looks good but I haven't tried it yet.

Oboe.js is here and it certainly projects maturity.

Don't know whether this is a bug or intended

But, it looks like nested objects break. See, e.g., http://dccode.org/browser/sections/1-206.02.json

allow pasting of URL instead of JSON body

fetched with CORS, error out if it doesn't work.

specifically, don't try JSONP

Command Line Interface

Any thoughts about enabling this in the command line?

Support upload of files

Drag and drop, or input box.

Local storage for downloaded data by ID

Cache it locally, to further minimize calls to the Github API. No editing allowed - IDs are created once and never altered, can be cached forever.

Graceful error handling

Show an indication if the parse fails. It should be mild enough that it's not annoying to hand-edit JSON and have it move in and out of a valid state. A mild red background to the textarea would suffice.

Select contents of CSV box when focused

typical

document the method

auto-selection of key, etc.

Download CSV doesn't give file name or extension in Safari

When used in Chrome, resulting file is "result.csv".

When done in Safari, the result is "Unknown" with no file extension.

This gets to be a hassle to manually have to add .csv each time before opening.

Only 1 line created with http://konklone.io/json/

I am working with this set of ip addresses, when I copy them in, the conversion only creates 1 line. It should create many lines (1 for each ip address range). Can you look into this? I was using Chrome and selecting Create CSV file.

BUG with array

I just try to convert this JSON
{"a":"ciao","b":[0,3,5]}

and I get this CSV

(no column "a" and no title for the column "b")

Link to open in Google Spreadsheets (and other services)

How about an "Open in Google Spreadsheets" link as an alternative to downloading? Or other services?

Graceful error

Right now, it just displays nothing. Say something if the conversion fails.

Warn on pasting in content above a threshold

Use the paste event to capture probably-too-big data and warn the user that it may just crash their tab. Provide a way to disable the paste check so that users can try again anyway.

Experiment with permalinking to pasted content

Some possibilities for compression (before base64 encoding):

• https://github.com/imaya/zlib.js/blob/master/README.en.md
• https://github.com/beatgammit/deflate-js

nothing happens when I pasted json in the top box

There doesn't seem to be any submit event.

Turn off JSON formatting for larger files

It's just not needed, and it slows things way way down. It actually crashed on me in the middle of my own Intro to JSON workshop the other day. Embarrassing!

Converting error

Hi! Im trying to convert example from wikipedia:

{
   "firstName": "Иван",
   "lastName": "Иванов",
   "address": {
       "streetAddress": "Московское ш., 101, кв.101",
       "city": "Ленинград",
       "postalCode": 101101
   },
   "phoneNumbers": [
       "812 123-1234",
       "916 123-4567"
   ]
}

and get only phoneNumbers: http://take.ms/rC6vm

Choose separator

Hello,

It would be nice to be able to choose the separator (comma, semicolon...).

Regards,

allow key override

Right now it just finds the first array field at the top level and uses that as the "record". But for something like

http://project-open-data.github.io/schema/1_0_final/single_entry.json

That doesn't work. Allowing an override of which key to use as the top (which in2csv, this project's inspiration, does) would solve this.

Command line version via npm

Not to compete with csvkit exactly, but it might be useful to take the existing JS and wrap it up in an npm module. If it's structured right, then any improvements to the browser version should improve the npm version without any extra work (beyond an npm publish command).

Low priority. But if the JSON is too big and we warn the user (#29) then maybe we can point them to this. It's nice to have an alternative if people want to process hub.healthdata.gov/data.json.

Nested objects make Firefox hang on line 49

Enter the following JSON:

{"foo": "bar", "sub": {}}

It will make Firefox hang at

        for (var key in next)

Download link won't work in IE

According to caniuse and my own testing, IE doesn't support the a[download] attribute, that allows specifying client-side that the linked content should be downloaded rather than viewed by the browser.

I don't think I can fix this, but I can at least remove the link and change the wording to suggest what to do instead (and I'm not sure what that would be, unless it's "paste it into notepad").

Allow custom filenames

More useful so that people distributing permalinks can make it so people download the file as something other than result.csv.

Support nested JSON

Please use the JSON at the below link to test. Here, looking at the result, group should be a column and not a row - also most columns should be rows:

http://konklone.io/json/?id=c2a83441af8b9421476e

Link to email or tweet me with a problem

Possibly with a link to a gist with an error report I can look at.

New lines

I think new lines (pretty JSON) in the JSON break the conversion.

Permalinks to conversions

To link to what particular JSON looks like in the converter.

Probably needs to support URLs first.

Also, ensmallen the JSON paste box, emphasize the output more than the input.

Unicode?

How does that work, especially with data: URIs?

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Base64_encoding_and_decoding#The_.22Unicode_Problem.22

Show formatted version of JSON?

Perhaps not by default, but an option to JSONView-ize the given JSON, in-browser. And, if this is turned on, it should be incorporated into the permalink.

The end result should be that you can hand someone a URL that shows them, in a visual manner, the input JSON and the output CSV.

How to handle no array?

Owen Boswarva notes that this JSON doesn't work.

With pretty formatting (and excerpted), it's:

{
  "petition":{
    "id":60616,
    "postal_districts":{
      "SA13":1,
      "W4":1,
      "RG1":2,
      "CV7":2,
      "BS35":2,
      "LN6":2,
      "DY4":1,
      ...
    }
  }
}

What's the right outcome here?

Convert on paste

I couldn't get this to work earlier, but I'm sure it can.

Add links to JSON Formatter and JSONView

Depending on the browser. To encourage people to see JSON in its more natural form.

CSV output causes problems for some apps

The output we produce for https://www.opm.gov/data.json (http://konklone.io/json/?id=9415277) is screwing up everyone except LibreOffice (gnumeric, Excel), because some fields have commas, even though it appears totally valid.

At least determine conclusively whether the output is faulty, or if there's anything the app can do in its output to improve interoperability.

Converting json to csv files for very larg files

I can convert the json to csv in the web browser but i have a very large files and i tried using | in2csv -f json -v > data.csv and i donot get all the columns which i get through the browser. How should i specify the code if am using a curl command? I checked the documentation but there is not enough explanation on converting the json to csv.

Look for the array two levels deep

This example has a main array that's two levels deep:

http://konklone.io/json/?id=9457288

I'm open to adjusting the algorithm to look two levels down. Maybe there are other heuristics to determine whether that's good (like < 5 keys at that level or something)?

display tabular CSV

In addition to the raw text. Default to tabular rendering.

Advanced override using JavaScript

Allow advanced users to provide a snippet of JavaScript that does custom mapping of "rows". Necessary to handle cases like the one described below (and others that have been reported).

Original ticket:

https://raw.github.com/csaid/economist_poll/master/survey_results.json

This is the file I'd like to play with. I paste it into the browser and just get a csv that is one row by 4,000. This isn't my JSON, but am curious if it's the person who compiled it's fault or some kind of quirk of the parser.

Thanks!

Drop CSV into new Google Doc?

Could be useful to offer an option to dump the table-ified JSON into a new Google Doc. Would probably require authorization from the user (a pain, I'm sure) but this would let a user grab JSON, edit it as needed, and then call on the edited data as a web service (e.g., using something like Tabletop) without ever leaving the browser. I can imagine this being especially useful for GeoJSON, where people (okay, me) often download a basic GeoJSON file (say, all the states in the US) and then want to add data on top of it (say, a new column with per-capita income) and use that data in a webapp.

jquery.min.map path not found

Please check the resource paths on your server, my browsers couldn't seem to find jquery-1.10.2.min.map.

GET http://konklone.io/json/assets/jquery-1.10.2.min.map 404 (Not Found)

Different URL?

It's running on Github Pages, so it's at konklone.io, but I don't use konklone.io for anything else. Is there a better place I could put this? Custom domain? At konklone.com?

have a more prominent note pointing to csvkit docs

for those w/ big files who might want to learn the next step

Handling UTF-8 Characters

There seems to be an issue handing UTF-8 characters, for instance "Reference “Resetting " is converted to "Reference “Resetting"

Seems to get caught up on curly quotes and other UTF-8 special characters.

Otherwise I like your app better than others (https://json-csv.com/) - it more logically creates a CSV than alternatives. However, json-csv.com handles UTF-8 special characters...

Valid JSON (129,002 characters) not converted correctly

The following JSON: http://mtgjson.com/json/KTK.json
Validates via: http://jsonformatter.curiousconcept.com/
But only 16 rows of data is converted by your script...

The reason is that the JSON has multiple nested arrays of data. I think some kind of alert notice should be issued so users know that the data is being truncated. Alternatively, the script keep the nested arrays, but leave them as one long csv field.

Support big files

Just a thought, but this would be possible with filereader-stream, binary-csv, and filesaver, though with semi-limited browser support.

Recent change to CSV format?

Hi. We have been transforming JSON files to CSV at your site (thanks!). It placed the variable labels and then the values in two two nice rows…but today it is just returning a single word from the file - exactly the same files that last week it converted as described. Has there been a recent change? Thanks very much. Tom11111

Chrome plugin to visualize JSON

Per this Twitter exchange, I think a browser extension that did the following would be awesome:

1. User navigates to raw JSON file
2. Clicks the button for this magical plugin
3. A table is appended to the top of the page showing the first 10 records in the JSON file
4. A button beneath that lets you see more records, or all the records (up to, say, 200 or something reasonable)
5. Optionally, you can download the whole thing as a CSV

Why? Basically, this JSON>CSV tool really drives home the value of using a tabular view to preview the contents of JSON - make sure you got the right fields, see what format different fields are in, get a sense of the length of different fields (like a "title", e.g.). Basically, this pulls the "preview as a table" functionality of JSON>CSV into its own bit of functionality and lets you deploy it without copy-pasting anything.
