Frequently Asked Questions
Your CSV should have columns for start time, end time, and subtitle text. Common formats include: 'start_time,end_time,text' or 'timecode_in,timecode_out,dialogue'. Timecodes can be in seconds (120.5) or HH:MM:SS format (00:02:00).
Yes, if your CSV has a speaker column, the converter can format it as '[Speaker Name]: dialogue' in the SRT subtitle text, which is standard practice for accessibility and multi-speaker content.
No. The CSV to SRT conversion happens entirely in your browser using JavaScript. Your files never leave your device, ensuring complete privacy for your subtitle data.
All major video editors support SRT files: Adobe Premiere Pro, Final Cut Pro, DaVinci Resolve, Avid Media Composer, HitFilm, and Filmora. SRT is the most widely compatible subtitle format.
Timecodes can be in seconds (decimal allowed, e.g., 45.750) or HH:MM:SS format (e.g., 00:01:23). The converter automatically detects the format and converts to the standard SRT timecode format (HH:MM:SS,mmm).
Yes, if your CSV has language or track columns, you can process multiple subtitle tracks. Each track should be in a separate CSV file for conversion to individual SRT files.
Since conversion happens in your browser, the limit depends on your device's memory. Most subtitle CSV files (even for feature-length content) are under 1MB and convert instantly.
Yes, the generated SRT files follow standard SubRip format and are compatible with YouTube's subtitle upload feature, Vimeo closed captions, and other video platforms that accept SRT files.
Basic SRT formatting is supported if your CSV includes HTML-like tags: <b>bold</b>, <i>italic</i>, <u>underline</u>. The converter preserves these formatting tags in the SRT output.
The converter processes subtitles in the order they appear in your CSV. If you have overlapping timecodes for multiple speakers or simultaneous dialogue, ensure your CSV is sorted by start time for best results.
Use UTF-8 encoding in your CSV file to ensure special characters, accents, and non-English text display correctly in the SRT output. Most modern spreadsheet apps save as UTF-8 by default.
