Hide a Message in a CSV lets you embed secret text inside a CSV using invisible spaces. Paste, encode, and export all privately and instantly in your browser.
How to Use:
- Paste your CSV data into the input box or import a file using the Choose File button.
- In the Secret message to hide field, type the message you want to conceal.
- Click Embed Message to encode your secret into the CSV. The tool hides each bit of the message as invisible spaces added at the end of CSV lines.
- The output updates instantly and flashes blue when changed.
- Use Copy Output to copy the modified CSV or Export to File to download it.
- Press Clear All to reset the message, CSV input, output, and character counter.
- Check the Total characters counter below the output to track content size after embedding.
What Hide a Message in a CSV can do:
Hide a Message in a CSV is a simple steganography tool that conceals text in plain sight. It hides binary data from your secret message by appending spaces to each line of your CSV. To the human eye (and most tools), the file looks unchanged but the message is still there, bit by bit. It’s perfect for embedding small notes, watermarking, or hiding simple instructions in datasets without breaking the format.
Example:
Original CSV:
id,name,email
1,Alice,[email protected]
2,Bob,[email protected]Secret message: OK
After embedding:
id,name,email
1,Alice,[email protected]␣
2,Bob,[email protected]␣(␣ represents a hidden space. Actual output contains no visible change.)
Common Use Cases:
Use this tool to watermark files, encode short metadata, or pass invisible messages in shared spreadsheets. It’s a quick, offline way to embed extra information in a dataset without affecting how the file works or displays.
Useful Tools & Suggestions:
Before embedding, Compress a CSV File can help make room for the hidden bits. And if you ever want to clean things up again, Remove Unwanted Characters is great for scrubbing the noise back out.
