SRT Subtitle Importer/Exporter is a Blender add-on from PoYakong that moves SRT subtitle files between disk and the Video Sequence Editor. Both directions run from the VSE menu under SRT, with Import bringing subtitle files in as text strips and Export sending them back out.
On import, the add-on automatically detects the scene's frame rate so subtitle timing stays precise. You can set a text strip as a standard subtitle template and apply it to all imported subtitles, and customize subtitle titles using an index iterator with the {index} syntax. Export selects all text strips in the scene with a single click and writes them out as a standard SRT file.
The add-on is listed here as compatible with Blender 5.0 and newer, while the developer's page states support for Blender 4.2 and later. It's distributed under the GNU General Public License v3.0 or later and requires no special permissions.
