Key Differences

"Through" is used to express movement within a bounded space, suggesting a passage from one end or side to another; on the other hand, "into" implies entry into a space or object, emphasizing the transition from outside to an interior point.
When describing time, "through" can denote a duration, covering a continuous period, such as "Monday through Friday," whereas "into" can be used to indicate a point in time when something extends or continues, as in "late into the night."
In the context of transformations, "through" might be used to denote the process by which something changes, like "through a series of events," while "into" typically indicates the result of a change, such as "transformed into a butterfly."
"Through" often suggests a medium or an intermediary in communication or perception, such as "heard through the grapevine," while "into" can indicate a focused involvement or deep engagement, such as "looking into a matter."
With transportation or motion, "through" implies passing directly within and out of a medium or area, like "driving through a tunnel," in contrast, "into" signifies entering a specific place or context, like "walking into a room."
