Finding differences or similarities across multiple lists

Sometimes you just need to know: which of these things is not like the other?

Deduplicating across lists is a super common, yet surprisingly difficult task. You've got two lists of client ids and you only want the uniques across both lists, or you only want to know which ids from the first list aren't present in the second. How do you do it?

You can let Parabola do the heavy lifting for you on this one. Our list contains step is super powerful and can address practically all variations on this problem type. As with all of these examples, it's important to keep in mind that these are just a taste of what you can build in Parabola. If you think Parabola can't solve your use-case, reach out to us on Intercom (the chat thing on our site) - we can figure it out together. We're very fun to talk to.

Get your data into Parabola

Let's just be clear on this from the start: if your data is on a computer somewhere, you can probably get it into Parabola. We directly integrate with twenty commonly-used services and we also support CSV/Excel file uploads, but true power lies in our generic API Import step: this step lets you connect to just about any web service with a standard REST API. We're pretty confident you'll be able to plop your data into Parabola.

The power of "list contains"

The main logic in this flow comes from Parabola's list contains step. That step takes as input two lists, and outputs entries that match the conditions specified in its settings panel. By default the step will output entries that appear in both input lists, but settings allow lots of flexibility:

–You can add arbitrarily many rules, i.e., match items along multiple conditions.

–The step can output items that do not match any or all of your rules.

–The step can be configured to be case sensitive or case insensitive.

–You can use fuzzy matching as part of rules, and can optionally configure the fuzziness as a percentage.

–(For debugging) the step can be configured to output a column indicating how a match was achieved.

Get your data where it needs to go

Now you're probably going to want to send your data somewhere else, right? We knew it.

We made it as easy to get data out of Parabola as it is to get data in. We're directly connected to fifteen external services (and also CSV + Excel downloads), but again the power lies in our generic API Export. We made a list of all the services that definitely play nice with our API Export, and have little snippets you can copy to get started. As a last resort, you can always reach our guy Brian on Intercom.
