如何批量为表格列中的编号添加指定前缀文本

Got it, let's break down how to batch add that specific prefix to all your IDs—here are a few straightforward methods depending on what tool you're working with:

If your IDs are in a spreadsheet column, this is the quickest no-code option:

• Let's say your raw IDs are in column A. In cell B1 (the first row of an empty column), enter this formula:
  ="0x8604808b824c4444fe4df3f94850acd584c5ad7d|"&A1
• Press Enter, then grab the small fill handle (the square at the bottom-right of B1) and drag it down to apply the formula to all rows with IDs.
• To replace the original column with the prefixed values: Copy the entire B column, right-click column A, and select Paste Values (this removes the formula and keeps only the final text).

Perfect if you've copied the IDs into a plain text file (one ID per line):

• Open the text file in your editor, then open the Find/Replace panel (use Ctrl+H on Windows/Linux, Cmd+H on Mac).
• Enable Regular Expression mode (look for a .* icon or toggle in the panel).
• In the "Find" field, enter ^ (this matches the start of every line).
• In the "Replace" field, paste your full prefix: 0x8604808b824c4444fe4df3f94850acd584c5ad7d|
• Click Replace All—every ID will now have the prefix added automatically.

If you're dealing with hundreds/thousands of IDs and want to automate the process, a quick Python script works great:

• First, save your raw IDs in a text file named ids.txt, with one ID per line.
• Create a new Python file (e.g., add_prefix.py) and paste this code:

# Define your fixed prefix
PREFIX = "0x8604808b824c4444fe4df3f94850acd584c5ad7d|"

# Process the input file and write to a new output file
with open("ids.txt", "r") as input_file, open("prefixed_ids.txt", "w") as output_file:
    for line in input_file:
        # Strip extra whitespace/newlines and skip empty lines
        cleaned_id = line.strip()
        if cleaned_id:
            output_file.write(f"{PREFIX}{cleaned_id}\n")

• Run the script, and you'll get a new file prefixed_ids.txt with all your IDs prefixed correctly.
