Step-by-Step Guide
Extracting Text Before a Character
1. Identify the Target Character: Determine the character before which you want to extract text (e.g., a comma, space, or dash).
2. Using the LEFT and FIND Functions:
- Syntax: LEFT(text, FIND(character, text) - 1)
- Example:
- Assume cell A1 contains "John, Doe".
- To extract "John" (text before the comma):
=LEFT(A1, FIND(",", A1) - 1)
3. Using the LEFT and SEARCH Functions (case-insensitive):
- Syntax: LEFT(text, SEARCH(character, text) - 1)
- Example:
- Assume cell A1 contains "John-Doe".
- To extract "John" (text before the dash):
=LEFT(A1, SEARCH("-", A1) - 1)
Extracting Text After a Character
1. Identify the Target Character: Determine the character after which you want to extract text.
2. Using the MID and FIND Functions:
- Syntax: MID(text, FIND(character, text) + 1, LEN(text))
- Example:
- Assume cell A1 contains "John, Doe".
- To extract " Doe" (text after the comma):
=MID(A1, FIND(",", A1) + 1, LEN(A1))
3. Using the RIGHT and FIND Functions:
- Syntax: RIGHT(text, LEN(text) - FIND(character, text))
- Example:
- Assume cell A1 contains "John-Doe".
- To extract "Doe" (text after the dash):
=RIGHT(A1, LEN(A1) - FIND("-", A1))

Example
Imagine you have a list of email addresses in Column A, and you need to extract the usernames (text before the "@") and the domains (text after the "@") separately.
Step-by-Step Process
1. Data in Column A:
- A1: [email protected]
- A2: [email protected]
- A3: [email protected]
2. Extract Usernames (Text Before "@"):
- In cell B1, use the formula:
=LEFT(A1, FIND("@", A1) - 1)
- Drag the formula down to fill cells B2 and B3.

- Results:
- B1: john.doe
- B2: jane.smith
- B3: info
3. Extract Domains (Text After "@"):
- In cell C1, use the formula:
=RIGHT(A1, LEN(A1) - FIND("@", A1))
- Drag the formula down to fill cells C2 and C3.
- Results:
- C1: example.com
- C2: company.org
- C3: mywebsite.net

Advanced Tips
1. Handling Multiple Occurrences of the Character:
- If the target character appears multiple times, use FIND or SEARCH with additional parameters or helper columns to identify the correct position.
2. Combining with Other Functions:
- Combine with TRIM to remove leading/trailing spaces:
=TRIM(MID(A1, FIND(",", A1) + 1, LEN(A1)))
- Use IFERROR to handle errors gracefully:
=IFERROR(LEFT(A1, FIND("@", A1) - 1), "No @ symbol found")
3. Dynamic Extraction with Variable Lengths:
- For variable-length text, use LEN in combination with MID, LEFT, and RIGHT to dynamically adjust extraction lengths.
4. Extracting Multiple Parts:
- To extract multiple parts of text, use nested FIND or SEARCH functions. For example, extracting the domain without the top-level domain:
=MID(A1, FIND("@", A1) + 1, FIND(".", A1, FIND("@", A1)) - FIND("@", A1) - 1)
