Import/Export for Scraper Chrome Extension

These files are a way to import and export fields entered in Chrome Scraper extension:

https://chrome.google.com/webstore/detail/scraper/mbigbapnjcgaffohmbkdlecaccepngjd?hl=en

Even when Presets option allows to save all fields, it is not apparent how to share presets between different installations, this is then a very rough attempt.

After exploring local storage for extension I saw that presets are stored there, so they can be copied and merged as a JSON would be merged:
