How to map keywords to emojis
Enter a caption and Emoji Mapper replaces recognized keywords with emoji values in the read-only output. Words such as love, coffee, and pizza use the built-in mapping. Tone chooses Happy, Neutral, or Angry values, and Instagram Style changes the caption layout.

How to add emojis to text with Tone
Each built-in keyword has three values. The slider groups them as Happy, Neutral, and Angry, so the same word can produce a different emoji while the other text stays unchanged.
Input: I love coffee and pizza
Tone: Happy
Output: I ❤️ ☕ and 🍕Matching ignores letter case and uses word boundaries. A keyword still matches beside punctuation, while unmatched words stay as entered. The script checks longer keys before shorter keys, so a longer custom phrase takes precedence when both keys could match.
How custom emoji mappings are read
Open + Custom Mappings and enter one rule per line. Put either an equals sign or a colon between the keyword and its replacement.
coffee = ☕
campaign : 🚀Blank or malformed lines are ignored. Keys are compared without case differences, and a later rule replaces an earlier rule with the same key. Custom rules override built-in keywords. Emoji values are inserted as written, so Tone does not change a custom value.
What Instagram Style changes in a caption
When Instagram Style is enabled, each non-empty input line is trimmed. The script splits after a period, exclamation mark, or question mark followed by whitespace, joins the pieces with blank lines, and appends three dot-separator lines. With the option off, keyword replacement keeps the input's existing line structure.
Upload accepts the file types listed in the file control: .txt, .csv, .log, .md, and text/plain. The mapping script reads the page fields and makes no network request with the entered text, so the transformation stays in the browser tab.
Examples with captions and replies

When a different text tool fits better
Use Emoji Mapper for keyword-to-emoji substitutions. In Text Transformation Tools, choose Find and Replace Text for literal or regular-expression replacement, HTML Entity Encoder / Decoder for entity references, or Slug Converter when the output should be a URL slug.

Paste text into the input area. Emoji Mapper replaces recognized keywords with built-in emoji values, and the output updates when you change the text, Tone, or custom mappings.
Can I add my own emoji mappings?
Open + Custom Mappings and enter one keyword = emoji or keyword : emoji rule per line. Custom rules override built-in mappings with the same keyword.
Does Emoji Mapper replace parts of longer words?
Replacements use word boundaries, so a keyword must match as a complete word or phrase boundary. Text with no matching keyword stays unchanged.
Does Instagram Style add emojis to text?
Instagram Style changes the layout after keyword replacement. It separates sentence-like lines with blank lines and appends three dot-separator lines.
Does Emoji Mapper send my text anywhere?
The page script performs the mapping in the browser and contains no network request for the entered text. The output is produced from the page fields.
