Batch TXT to CSV Converter
Convert multiple text files to CSV in one pass. Drop up to 50 .txt or .csv files, choose a single output format, and download every converted file — all processed locally in your browser.
Drop up to 50 files or click to choose
.txt, .csv, .tsv, .json — converted in your browser
Add up to 50 files above, set the output format once, then Convert all and Download all.
Convert many text files to CSV together
When you have a folder of exports, logs or lists, converting them one by one is slow. This batch convert text file to CSV tool processes up to 50 files at once: add them, pick the output format, and every file is converted with the same settings.
Each file is read and converted in your browser — nothing is uploaded — and you can download results individually or use Download all. The same options that power the single converter (delimiter detection, header, encoding, Excel-safe numbers) apply to the whole batch.

How to batch convert text files
Add your files
Drop up to 50 .txt or .csv files onto the box, or click to choose them. They are queued locally.
Set the output once
Pick CSV (or another format) and any options like UTF-8 BOM or header — they apply to every file.
Convert and download
Click Convert all, then download each result or use Download all to save them together.
Input and output example
Every file in the batch is converted with the same settings; here a tab file becomes CSV.

B2,9How batch conversion handles your files
A few details worth knowing before you run a large batch.
Consistent settings across files
Every file in the queue is converted with the same output format, delimiter handling and options. This is ideal when a set of files shares a layout — you standardize them all in one step. If files differ a lot, convert them in groups.
Per-file download and Download all
After converting, each row in the list gets its own download link, and the output keeps the original file name with the new extension. Download all saves every converted file in sequence.
The 50-file limit
Batches are capped at 50 files to keep everything responsive in the browser. For more, run a couple of batches. Very large individual files still depend on your device’s available memory.
Privacy for bulk data
Because all conversion is local, batch processing is safe for sensitive datasets — none of the files are sent to a server.
Tips and edge cases
- Group files that share a layout so one set of options fits them all.
- Tick UTF-8 BOM before converting if every file will be opened in Excel.
- Need scripted bulk conversion instead? See PowerShell or Linux.
Where batch conversion shines
Batch conversion is ideal for recurring chores — nightly exports, weekly reports, or a backlog of saved text files. Because the work is local, you can queue confidential files without an upload step, and the per-file naming means results drop neatly back beside their sources. When a layout changes, adjust the options once and re-run the whole set instead of editing files individually.
