Workflow notes

How to use this CSV to SRT tool

CSV caption files often come from transcript exports, spreadsheets, and review systems. This converter reads start, end, and text columns, preserves quoted caption text, turns escaped line breaks into SRT lines, and exports numbered SubRip cues locally with no upload.

  1. Add a supported subtitle file. Upload or paste a supported subtitle file (.csv, .txt), or load the sample input to see the expected structure.
  2. Run the CSV to SRT tool. Use the browser-based converter or repair action to process the subtitle file locally on your device.
  3. Review and download the output. Check the first few cues, the middle of the file, and the final cue before copying or downloading the result.

Input and output checklist

  • Use a complete subtitle file with valid cue timing when possible.
  • Keep a copy of the original file before replacing it in your workflow.
  • Review the first few cues, the middle of the file, and the final cue after export.
  • Test the downloaded output in the destination player, editor, or upload form.

Common mistakes to avoid

  • Leaving commas unquoted inside caption text cells.
  • Exporting transcript text without start and end timing columns.
  • Uploading the SRT output before validating timing and line breaks.

All processing runs in your browser, so the subtitle or video file does not need to be uploaded to a server. That is useful for client review files, unreleased videos, internal training material, and other caption workflows where the text should stay on your device.

When to use this tool

Use this free CSV to SRT converter when transcript exports, spreadsheet rows, or caption QA files need standard numbered SubRip output.

  • Convert transcript exports with start, end, and text columns into SRT.
  • Move spreadsheet-edited caption rows back into subtitle timing format.
  • Create upload-ready SRT from CSV files exported by caption tools.
  • Prepare CSV caption data for SRT validation, cleanup, or review workflows.

FAQ

How do I convert a CSV subtitle file to SRT? +

Open the CSV to SRT converter, paste or upload rows with start, end, and text columns, and export them as numbered SRT cues.

What CSV columns are supported? +

The converter supports header columns such as start, end, and text. Without a header, it reads the first three columns as start time, end time, and caption text.

Can CSV captions contain commas or line breaks? +

Yes. Put text that contains commas inside quotes, and use escaped line breaks such as \n inside a text cell for multi-line SRT cues.

Are CSV subtitle files uploaded to a server? +

No. The CSV to SRT conversion runs locally in your browser, so the subtitle rows stay on your device.
