Convert CSV to JSON and Check the Data Before Import
A careful CSV-to-JSON workflow covering headers, quoted commas, embedded line breaks, empty cells, and validation before an application import.
Base64 Encode/Decode
Encode or decode Base64 strings instantly
Overview
Encode or decode Base64 strings instantly
Use the Base64 Encode/Decode when you need the specific operation described above. Choose the input and options that match your intended output, then check the result before using it elsewhere.
Usage Steps
Paste or upload the source data
Load the original text, spreadsheet, or file into the browser-based converter.
Select the target format
Choose the output type you want, including JSON, CSV, Base64, or a color code conversion.
Transform the result
Run the conversion instantly in the browser and review the generated output before downloading.
Use the output safely
Download or copy the transformed content and move it into your workflow with confidence.
Technical Context
Technical context
Converters must preserve delimiters, character encoding, numeric-looking identifiers, and format-specific rules. Inspect representative input and output records before using converted data in another application.

Quality checks and limitations
Validate the output with the application that will consume it. Syntax validity alone does not confirm that every field has the intended meaning or data type.
The tool is a focused utility rather than a substitute for reviewing the final file or data in its destination. Keep an unchanged source when the input is important, and use the relevant specialist software for requirements the page does not claim to support.
Frequently Asked Questions
What is Base64 encoding used for?
Base64 turns binary or Unicode data into plain ASCII characters so it can travel safely through systems that only accept text, such as email bodies, JSON payloads, and data URLs.
Is Base64 encryption?
No. Base64 is reversible encoding, not security — anyone can decode it. Use real encryption for anything confidential.
Is my data sent to a server when I encode it?
No. Encoding and decoding both run in your browser with the built-in btoa/atob APIs, so the text you paste never leaves your device.
Why do I see an error when encoding emoji or accents?
Classic btoa only handles Latin-1. YaaftAi promises UTF-8 safe encoding, so make sure UTF-8 mode is selected for non-ASCII characters.
Can I decode a Base64 data URL from an image?
Yes. Paste the part after the comma in a data: URL to decode it back into text, or encode text to build your own data URL.
Is my data uploaded when I convert a file here?
No. Conversion happens in your browser, so spreadsheets, JSON payloads, and images are never uploaded to a YaaftAi server.
