Documents and bulk text

Convert whole files.

Upload a Word document, Markdown file, CSV column, or paste hundreds of lines — and convert them all at once. Runs entirely in your browser. Your files never leave your device.

Style guide

Input

⬆

Drop a file or click to upload

.txt · .md · .csv · .docx

or paste

Output

Each line converted independently. CSV: first column used.

How it works

Privacy by design.

Runs in your browser

The .docx parser (mammoth.js), the CSV reader (Papa Parse), and the case-conversion engine all run as JavaScript on your machine. Nothing is uploaded.

ii.

Line-by-line processing

Each non-empty line in your input becomes a separate conversion. Blank lines and CSV headers are preserved untouched.

iii.

Download a clean file

After conversion, click the download icon to save the output as plain text. Use it as a new column in your spreadsheet or paste it back into your document.

What's supported

Four file formats.

Format	Behavior
.txt	Each line converted; blank lines preserved.
.md	Read as plain text. Markdown syntax (headings, lists) is preserved as characters; only the text content is recased per the selected mode.
.csv	First column extracted; each cell converted; output is one value per line.
.docx	Text extracted via mammoth.js, then each paragraph converted as a line. Original formatting is not preserved in the output.
