Find and replace a string at a certain position

⭐ Find and Replace String at Position - Explanation & Examples

The Find and Replace String at Position tool allows you to replace a specific search string only at a defined location within each line. You can choose to replace the search word at the beginning of a line, at the end of a line, or at an exact character position. This makes the tool ideal for structured, line-based text editing.

⭐ What Does This Tool Do?

This tool lets you:

• Replace a specific search word at the start of a line
• Replace a specific search word at the end of a line
• Replace a search word at an exact character position
• Process multiple lines at once
• Ensure replacements only happen at the selected location

⚙️ How It Works

1. Paste or upload your text.
2. Enter the search word you want to replace.
3. Select where the search word must appear:
   • Beginning of the line
   • End of the line
   • Specific character position
4. Enter the replacement text.
5. The tool replaces the word only when it matches the selected position.

🔎 Example: Replace at the Beginning of a Line

Original Text:

ERROR: File not found
ERROR: Access denied
INFO: Process started

Search word: ERROR

Replace with: WARN

Position: Beginning of line

Result:

WARN: File not found
WARN: Access denied
INFO: Process started

🔎 Example: Replace at a Specific Character Position

Original Text:

ID-12345-XYZ
ID-67890-XYZ

Search word: 12345

Position: Character position 4

Replace with: 99999

Result:

ID-99999-XYZ
ID-67890-XYZ
