AppendToFile

FileTools

Security Level 2 - Write

SindByte tool execution flow: voice command, AI parse, execute, validate, result

Description

Add content to the end of a file - without losing the existing content! AppendToFile is the perfect solution for log files, data logs, and any scenario in which you want to accumulate information continuously.

The tool opens the file in append mode, writes the new content, and closes the file safely. No risk of data loss, no complex file management - just append and you're done!

Why This Tool Stands Out

Log Creation effortless
Data Accumulation continuous
Results depend on input, configuration and implementation. Verify behavior in your environment; no accuracy, security or performance guarantee is established here.
High Performance even with large files

Perfect for:

Developers who build logging systems; system administrators who maintain audit trails; data analysts who record time series; and anyone who needs to document data continuously. Ideal for server logs, application logs, and data tracking.

Workflow support; time savings depend on the task

Instead of having to open files, scroll to the end, insert content, and save, you add new entries with a single API call - atomically and safely.

JSON Parameters

filePath REQUIRED (String)The full path of the file. If the file does not exist, it is created automatically. Example: "C:\\Logs\\app.log"
content REQUIRED (String)The content to append to the end of the file. Line breaks must be included explicitly (e.g., \\n).
encoding OPTIONAL (String)The character encoding. Important: It must match the encoding of the existing file. Default: "UTF-8"

Example Call

{
  "tool": "AppendToFile",
  "params": {
    "filePath": "C:\\Logs\\application.log",
    "content": "[2024-01-15 10:30:00] INFO: User logged in\\n",
    "encoding": "UTF-8"
  }
}

Return Values

The tool returns an object with the following properties:

success (Boolean)
True if the append was successful
filePath (String)
The actual path of the file
bytesAppended (Integer)
Number of bytes appended
totalSize (Integer)
New total size of the file in bytes
error (String, optional)
Error message if the append failed

Example Usage

Step-by-step guide:

Create a log file or use an existing file
Define the content you want to append (e.g., timestamp + message)
Call the AppendToFile tool with the file path and content
The tool adds the content to the end of the file without overwriting existing data
Check the return values to confirm successful execution
