Upload your JSON file, preview your data and automatically convert it to a CSV file.
Upload a file Input a URL Paste data
Drop a file or click to select a file.
Convert up to 10 MB for free without creating an account. Uploaded data will only be used for the conversion and will be automatically deleted after converting.
JSON stands for JavaScript Object Notation and it's a plain-text data format primarily developed for use in JavaScript, but now widely used across the interwebs, specially in modern web APIs.
As stated by the RFC 8259, we expect strings in uploaded JSON files to be encoded in UTF-8.
If your file contains non UTF-8 characters, you might get an error when converting your data.
CSV stands for Comma Separated Values and is a plain-text file format that stores tabular data. CSVs are widely used to import and export data for all kinds of services for it's simplicity and ease of parsing.
CSV data will be delimited using a new line character (\n)
The value separator is the character used to separate each value inside a row.
For CSV files, as the name implies it is usually a comma, but you can choose a different one depending on your needs:
CSV files don't have a standard way of defining empty or NULL values, like SQL or JSON files.
Usually we assume a blank value means empty, but you can set this yourself to something else, for example "NULL".
All data will be encoded using the UTF-8 character encoding scheme.
How does the file limit work?
You can upload files up to 10 MB without creating an account. The limit is increased to 50 MB if you sign up with a free account.
Subscribe to the Pro plan if you need to upload files up to 1000 GB.
We pride ourselves in building a converter that's easy to use, but security is also our top priority.
We understand that some data uploaded might be sensitive, so we ensure that your data is only used for the conversion.
We follow widely accepted industry standard practices when it comes to security:
HTTPS is enforced for all communications with our server
We enforce a strict access policy and employees or external collaborators never have access to user data
All data is always encrypted at rest
All data is automatically deleted forever 24 hours after being uploaded.
We allow time days before deleting files just in case you're not done with the data, if you're done with converting a file and want to delete it right away, you can do it yourself through the API.
Note that all files files uploaded without an account are acessible by a unique URL that is hidden but accesible by anyone, so we recommend you to sign up with an account if you want your files to be private, only your account will be able to access your files.
Do you provide an API?
You can upload files, queue and check the progress of conversion jobs with our API. Check out the API documentation for more detail.
Do you offer a trial?
We don't offer a trial plan at the moment.
You can trial a subset of your data with the Free plan.
All plans provide the same conversion features.
Do you offer refunds?
We can offer you a refund when:
You just paid to start or renew a subscription and you didn't use the service yet.
You forgot to cancel your subscripition, we'll give you a refund up to the last 3 months with no usage of the service.
Where do I get my API key?
You'll get an API key when you sign up, find it in your account page.
How do I cancel my subscription?
Go to your account page and find the Billing section, there you can downgrade to the Free plan. Your plan will be cancelled immediately and you won't be charged again.
Do you have any SDKs for your API?
Unfortunately, we don't have any language specific SDKs yet, so you'll have to use a standard HTTP client for it.
