を通じて | Through and Throughout in Japanese

Two Senses

1. By means of / via — a medium or intermediary.

2. Throughout a period — the whole span, without a break.

Near-interchangeable, with a slight lean:

Pattern	Lean
を通(つう)じて	the medium matters; more common for spans of time
を通(とお)して	the speaker's own active effort in going through it

経験(けいけん)を通(とお)して学(まな)んだ feels slightly more personal than を通(つう)じて. Neither is wrong in most sentences.

Both cover "by means of", and the split is what kind of means:

Pattern	Means
によって	a method or an agent
を通(つう)じて	a channel you pass through

A person you go via takes を通(つう)じて; a person who performs the action takes によって.

Formal. In speech, で or から often does the job for sense 1.
