Frequently Asked Questions
Your Excel file should have columns for start time, end time, and subtitle text. Use column headers like 'start_time', 'end_time', 'text' or 'timecode_in', 'timecode_out', 'dialogue'. Timecodes can be Excel time format (h:mm:ss), decimal seconds (120.5), or text format (00:02:00).
Yes, the converter processes the first worksheet by default. If you have multiple subtitle tracks in different sheets, save each sheet as a separate XLSX file or copy the desired data to the first sheet before conversion.
Excel time format (h:mm:ss) works best and is automatically detected. You can also use decimal seconds (45.750) or text format (00:01:23). Avoid mixing formats within the same column for consistent conversion results.
No. The XLSX to SRT conversion happens entirely in your browser using the SheetJS library. Your Excel files never leave your device, ensuring complete privacy for your subtitle data and any confidential content.
Yes, if your Excel file has a speaker column, the converter formats it as '[Speaker Name]: dialogue' in the SRT output. Basic HTML formatting tags (<b>, <i>, <u>) in Excel cells are preserved in the subtitle text.
All major video editors support SRT files: Adobe Premiere Pro, Final Cut Pro, DaVinci Resolve, Avid Media Composer, Adobe After Effects, HitFilm, Filmora, and OpenShot. SRT is the industry standard subtitle format.
Since conversion happens in your browser, the limit depends on your device's available memory. Most subtitle Excel files (even for feature-length content with detailed notes) are under 5MB and convert instantly.
Yes, many professional transcription services (Rev Professional, 3Play Media, Vitac) export detailed timing data in Excel format. This converter transforms their structured output into standard SRT files for video production workflows.
Yes, the generated SRT files follow standard SubRip format and work with YouTube's subtitle upload, Vimeo closed captions, Facebook video captions, LinkedIn video subtitles, and other platforms that accept SRT files.
The converter reads calculated cell values, not formulas. If your Excel file uses formulas to calculate timing (e.g., =A2+5 for end time), ensure the formulas are calculated before conversion. Save and reopen the file if needed to update all calculations.
Excel cell comments aren't included in the SRT output since subtitle files only support text content. However, you can create a separate column for director notes or production comments that won't appear in the final subtitle file.
Use column headers in row 1: 'start_time', 'end_time', 'text', and optionally 'speaker'. Sort data by start time for proper subtitle sequencing. Use Excel's time format for timecodes and avoid empty rows between subtitle entries for clean conversion.
