In a few React.js projects, we have huge JSON files, which are used for the filterable data in the frontend. To keep the frontend fast we decided on creating a small standalone API.
Sometimes we get data from customers as Excel files. These are then converted to JSON files to be able to be processed further. In the past, this was often a cumbersome task with many manual steps. With SQLite, we made this much easier and reduced the number of needed steps.
