Newline Delimited JSON

NDJSON or Newline Delimited JSON is a format designed to make streaming of JSON documents easier. Each JSON document is separated by a new line character, perfect to store a large amount of records.


SQL stands for Structured Query Language and is a standarized language used to communicate with almost all relational databases. It can be used to query, insert and manipulate data stored in a database.

Frequently asked questions

Are there limits to how much data I can convert?

You can upload files up to 50Mb without creating an account. The limit is increased to 100Mb if you sign up with a free account.

There are no limits with the pro plan, you only pay for the data your process.

How does the data limit work?

Depending on the plan you select, you'll have a different monthly limit. You can convert as many files as you want until you reach the limit for the month. Once the limit has been reached, you can either upgrade your plan or wait until the next month.

Is it secure?

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 uploaded files are automatically deleted forever 1 day after being uploaded.
  • All exports are automatically deleted forever 1 hour after being created.

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.

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. But you can convert smaller files with the Free plan to see if it's right for you.

All plans provide the same features.

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 cancel section, there you can cancel your subscription.

You subscription won't renew next time, but you'll be charged for the current usage so far.

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.
