Sitemap json lenght limit

i'm creating in excel a sitemap json with 14000 start urls. when I want to import it into webscraper it says that json is invalid.

For the time being I will just divide my big sitemap into several ones. Is there a way to make the character limit higher?

Hi!

Upcoming release will have a cap of 10,000 URL per sitemap. Meanwhile you can still split your URLs into parts and have a faster scraping using several tabs (scrape two sitemaps at once)
