I've created an app for conversions and exchange rates. Every day I need the exchange rate of a certain currency and I use the API free exchange and UiPath.
It's also used for the reconciliation of invoices.
I've used it for the creation of an onboarding bot for employees to be onboarded onto a website with a remote system. I used AWS and a virtual machine and created a Google Form from there, and used UiPath's computer vision to do onboarding activities and extract data from files. PDF files can then be entered into the remote system. UiPath can be used to fill the forms.
It can be used for web extraction tasks as well, for example, for booking flights, where you can extract the flight details for particular search criteria and place them into an Excel sheet.
It can also be used to extract data from invoices in order to populate an Excel sheet, for a portable format. I've created a process that used documents as a learning model and extracted the invoices, using logic to output the transactions.
Another use case I tried was extracting data from Amazon based on exact data. The same can be done on Linkedin using the Linkedin API. I'm fine-tuning and extracting data, putting the outputs on Google Sheets.
I've experimented with many use cases and automated many processes.
