Frequently Asked Questions
What is an SRT file?
SRT (SubRip Subtitle) is the most widely used subtitle format. It contains subtitle entries with sequential numbers, timestamps in HH:MM:SS,ms format, and the subtitle text. SRT files are compatible with most video players including VLC, Windows Media Player, and streaming platforms.
What CSV format does this tool require?
Your CSV must have three columns: start (start time), end (end time), and text (subtitle content). Times can be in seconds (e.g., 1.5), or SRT format (00:00:01,500). The first row should contain column headers.
How are time values converted to SRT format?
The tool automatically detects your time format. Decimal seconds (like 3.5) are converted to SRT format (00:00:03,500). If your times are already in HH:MM:SS format, they are preserved. Milliseconds are padded to 3 digits.
What happens to empty subtitle rows?
Consecutive rows with empty text are automatically merged. The tool extends the end time of the previous subtitle to cover the empty row's duration, reducing clutter in the final SRT file.
Can I use this tool for YouTube captions?
Yes! Export your caption data as CSV with start, end, and text columns, then convert to SRT. YouTube accepts SRT files for manual caption upload, making this tool perfect for preparing professional subtitles.
Is there a limit to the CSV file size?
The tool can handle CSV data with thousands of subtitle entries. For very large files, processing may take a few moments. All processing happens in your browser for privacy.
