Transforming Periods to Commas in SRT Files with JavaScript

Working with SRT files can be a bit tedious, especially when it comes to formatting timestamps and dialogue. One common task that users often need to do is change periods (.) to commas (,) in certain lines — particularly those containing timestamps. If you’ve ever found yourself needing to correct these punctuation issues, you're in the right place!

The Challenge

You might have an SRT file like the following:

In this example, you want to replace each period (.) in the timestamp section (the part before the second colon) with a comma (,).

The Solution

With JavaScript, this task can be easily accomplished through the use of the replace method along with a regular expression. Here's a breakdown of how to do it:

Step 1: Load the SRT Content

First, you need to ensure that your SRT content is accessible. For this solution, we're assuming the content is already loaded into a variable (str).

Step 2: Use the Replace Function

The key part of the solution is replacing the dots in the timestamps. Here’s how you can do it:

Explanation:

Regular Expression: /:[0-9][0-9]./g

: matches the colon before the seconds.

[0-9][0-9] matches two digits (representing the seconds).

. matches the period that follows.

The g flag means it will search globally through the string.

Replacement Function: This function takes each match and slices off the last character (the period) then appends a comma instead.

Step 3: Update the SRT Content

Finally, once you've created your new string with the revised punctuation, don't forget to update the DOM if necessary:

Conclusion

By implementing this simple JavaScript solution, you can quickly change periods to commas in your SRT files. Not only does this save you valuable time, but it also ensures your files are formatted consistently.

If you run into any issues or want to modify this function further, feel free to experiment with the regular expression and replacement logic. Happy coding!
