How do I convert a CSV file to SRT?

Use our CSV to SRT Converter to build a subtitle file from a table. Steps to convert CSV to SRT: Make sure your file has a start time, an end time and the subtitle text somewhere - the header wording is up to you Upload the CSV file If your file does not use commas, pick the matching delimiter Click 'Run Conversion' When the file is ready - download the SRT file

My file has an original and a translation. Which text column is used?

The first text column in the file, and the conversion result tells you which one that was. To export the other language instead, move its column in front of the first one or remove the column you do not need.

How do I write a subtitle that takes two lines on screen?

There are two ways, and both work: Put a line break inside the text value itself and keep the value quoted Add a continuation row underneath - leave the start and end fields empty and put the second line in the text column. It is appended to the cue above as a new line instead of being dropped Completely empty rows are skipped, so spacer rows in your file do no harm.

Which delimiters are supported?

Comma is the default. You can also convert files that use a semicolon, a vertical bar or a tab by choosing the matching delimiter before running the conversion. Pick the one your file actually uses - a mismatch makes the whole line read as a single column, and the columns can then no longer be told apart.

Can I go the other way and turn subtitles into a CSV?

Yes. Our SRT to CSV Converter exports an existing subtitle file into a table this converter reads without any renaming, which makes a full round trip possible: export to CSV, edit or translate in your spreadsheet software, then convert back to SRT. Both converters run in your web browser with nothing to install, uploads are encrypted in transit and files are deleted automatically after the conversion.

Subtitles Converters CSV Converters

Convert a CSV file into an SRT subtitle file ready for video players and editing software. Each row of your table becomes one subtitle cue, with its own start time, end time and text.

You do not have to reshape the file first. Column headers are matched by meaning, so the wording your subtitle editor, translator or export script used is very likely already understood - what works is spelled out below.

What Your CSV Needs

Only three things are essential: a start time, an end time and the subtitle text. Everything else is optional.

A start column and an end column - or a single column holding the whole range, such as 00:00:01,000 --> 00:00:03,000.
A text column - the words that appear on screen.
A numbering column is optional. Leave it out and the cues are numbered for you, in the order the rows appear.

Beyond that, the converter is deliberately forgiving:

Header wording is flexible and case does not matter. Start Time, Timecode In and START all mean the same thing.
Extra columns are ignored. Speaker names, a second language, reviewer notes, layer or track IDs can all stay where they are.
A title row above the header is fine. If the first line is a file name, an episode title or a note to a colleague, the real header row is found for you within the first few rows.
A bad row does not sink the file. Rows that cannot be read are skipped and the rest of the subtitles are still produced.

An optional type column is read when present; leave it out and every row is treated as a normal subtitle cue.

Column Names That Are Recognised

Letter case and surrounding spaces are ignored, so Index, INDEX and index are all the same header. These wordings are understood:

Column	Headers that work
Numbering optional	index, no, no., #, num, number, id, line, entry, entry #, serial, serial number, seq, sequence, cue
Start time	start, start time, start_time, in, in time, timecode in, tc in, begin, from
End time	end, end time, end_time, out, out time, timecode out, tc out, finish, to, until
Subtitle text	text, subtitle, subtitles, subtitle text, subtitle content, caption, content, dialogue, original

If your file has more than one text column - an original and a translation, say - the first one is used, and the conversion result tells you which column it took. To export the other language, move that column in front of the first one, or drop the one you do not need.

Prefer to start from something that already works? Download the sample file: sample.csv

A Real Export, Converted As It Is

Here is a file of the kind subtitle tools actually produce: a title on the first line, headers no one would call index or text, and a speaker column that has nothing to do with the subtitle file. Nothing here needs renaming.

Before - your table

Entry #	Start Time	End Time	Speaker	Subtitle Text
Episode 4 - English subtitles (final)
1	00:00:01,000	00:00:04,500	Narrator	Welcome to our video tutorial.

3	00:00:09,000	00:00:12,000	Host	Let's get started!

The same file as raw CSV text:

plaintext

Episode 4 - English subtitles (final)
Entry #,Start Time,End Time,Speaker,Subtitle Text
1,"00:00:01,000","00:00:04,500",Narrator,"Welcome to our video tutorial."
2,"00:00:05,000","00:00:08,250",Narrator,"Today we will look at file conversions."
3,"00:00:09,000","00:00:12,000",Host,"Let's get started!"

Timestamps in the HH:MM:SS,mmm form contain a comma before the milliseconds, so quote them in a comma-separated file.

After - the SRT file

plaintext

1
00:00:01,000 --> 00:00:04,500
Welcome to our video tutorial.

3
00:00:09,000 --> 00:00:12,000
Let's get started!

The title line and the speaker column are left out of the subtitle file, and the cues are numbered from 1 in row order. Delete the Entry # column entirely and the result is identical.

Time Formats You Can Use

Any of these work, and you can rely on the one your tool already writes:

HH:MM:SS,mmm - the SRT standard, for example 00:01:23,456
HH:MM:SS.mmm - a full stop instead of the comma, which also saves you the quoting in a comma-separated file
MM:SS,mmm - the hours part left out
HH:MM:SS - whole seconds, no milliseconds
HH:MM:SS:FF and HH:MM:SS;FF - SMPTE timecode, including the drop-frame form with a semicolon
Time values written by spreadsheet software - a cell that has been turned into a clock value is read as a time rather than rejected

One column holding both times. If your file keeps the range in a single field, such as 00:00:01,000 --> 00:00:03,000, that is understood too - no need to split it into two columns.

How to Convert CSV to SRT

Check that your file has a start time, an end time and the subtitle text somewhere. The header wording is up to you.
Upload the CSV file with the file picker above.
If the file does not use commas, choose the matching CSV file delimiter. Semicolon, vertical bar and tab are supported.
Click "Run Conversion".
Download the SRT file and drop it next to your video.

Subtitles in the finished file are numbered from 1 in the order the rows appear, so gaps or duplicates in your numbering column are corrected automatically, and a file with no numbering column at all works just as well. Sort your rows by start time and the output follows.

Subtitles That Take Two Lines on Screen

There are two ways to write them, and both work:

A line break inside the text value. Keep the value quoted and the break is carried through to the subtitle file.
A continuation row. Leave the start and end fields empty and put the second line in the text column. It is appended to the cue above as a new line rather than dropped - which is exactly what you want when a translation tool has split one cue across several rows.

Completely empty rows are skipped, so spacer rows and a trailing blank line do no harm.

What People Use It For

Post-translation import: translators deliver a CSV file - convert it straight to SRT and attach it to the video, headers and all.
Subtitles from a transcript: lay a script or transcript out in a spreadsheet with timings, export as CSV, and generate the subtitle file.
Round-trip editing: export with SRT to CSV, make your edits in a spreadsheet, and convert back here.
Automated pipelines: generate CSV from a database or a script, then convert whole batches of files at once.

Frequently Asked Questions

What columns does my CSV need?

A start time, an end time and the subtitle text. A numbering column is optional. Header wording is flexible - Start Time, Timecode In and In all mean the start of a cue - and letter case and surrounding spaces are ignored. Extra columns are ignored too.

Do I have to rename my headers to index, start, end and text?

No. The common wordings that subtitle editors and transcription tools export are recognised as they are, including Entry #, No., Cue, Start Time, Timecode Out, Subtitle Text, Caption and Dialogue. The full list is in the table above. If a header of yours is not on it, renaming that one column is enough.

Does my file need a numbering column?

No. If there is no numbering column, the cues are numbered from 1 in the order the rows appear. If there is one, its values are still replaced with clean sequential numbers, so gaps, duplicates or a counter starting at 0 are all fixed for you.

My file starts with a title line above the headers. Is that a problem?

No. A file name, an episode title or a note sitting above the header row is tolerated - the header row is located automatically within the first several rows.

What timestamp formats are accepted?

HH:MM:SS,mmm and HH:MM:SS.mmm, the shorter MM:SS,mmm, plain HH:MM:SS without milliseconds, SMPTE timecode as HH:MM:SS:FF (or HH:MM:SS;FF for drop-frame), and time values written by spreadsheet software. A single column holding a whole range, such as 00:00:01,000 --> 00:00:03,000, is understood as well.

My file has both the original and a translation. Which one is used?

The first text column in the file, and the conversion result tells you which one that was. To export the other language, move its column in front of the first one or remove the column you do not need.

What happens to a row with a broken timecode?

That row is skipped and the rest of the file is still converted, so one stray value no longer costs you the whole conversion.

My timestamps look wrong after editing in a spreadsheet. Why?

Spreadsheet software likes to reinterpret anything that looks like a time. Those cells are still read correctly, but a spreadsheet can round the milliseconds away when it rewrites them. Format the start and end columns as plain text before typing into them and the values stay exactly as you entered them.

Which delimiter should I use?

Comma is the default. Tab, semicolon and vertical bar are also supported - pick the one your file actually uses, because a mismatch makes the whole line read as a single column and the columns can then no longer be told apart.

How do I write a subtitle with two lines?

Either put a line break inside the quoted text value, or add a continuation row with empty start and end fields - its text is appended to the cue above as a new line.

Is it free, and is my file private?

Conversion is free to try, with larger files, batch conversion and API access covered by our pricing plans. Uploads are encrypted in transit, the source file is deleted right after the conversion, and the result is removed automatically within 24 hours.
