Text File Merger
Combine multiple text files in order with a custom separator
Text File Merger — what it does
Combine several text files into one, in the order you selected them, with a separator label placed between each file's contents. The separator is what keeps the result usable: without a marker between sections, a merged file gives no clue where one source ended and the next began.
When this tool helps
- Consolidating log files from several days or servers into one document for searching.
- Merging notes or transcript fragments captured in separate files.
- Combining code or configuration snippets into a single reference file.
How to use it
- Choose the text files in the order they should appear.
- Set a separator label.
- Merge the files.
- Download the merged TXT.
Accuracy, limits, and good practice
- Include the filename in the separator label where you can — provenance is exactly what gets lost the moment files are concatenated.
- Selection order determines the merge order, so rename files with numeric prefixes first if a strict sequence matters.
- Files should share an encoding. Mixing UTF-8 with a legacy code page produces mojibake in the merged result.
- Merge a copy, not the originals. Once concatenated, splitting the result back into its source files is manual work nobody enjoys.
Frequently asked questions
Does it work with CSV files?
It concatenates text, so each file's header row would be repeated. Use the CSV merger for tabular data instead.
Is there a file size limit?
Memory is the practical limit. Very large log sets are better merged with a command-line tool.
Can I merge files of different types?
Any plain text works. Binary files are not text and will produce unusable output.
Are line endings normalised?
Files are joined as they are, so a mix of Windows and Unix line endings carries through into the merged output.

文字檔案合併器能做什麼
把多個文字檔依你選取的順序合併成一份，並在每個檔案內容之間放入分隔標籤。分隔標籤正是讓結果可用的關鍵：段落之間沒有標記，合併檔就完全看不出前一份在哪結束、下一份從哪開始。
什麼時候用得上
- 把多天或多台伺服器的日誌整併成一份文件以便搜尋。
- 合併分散在不同檔案中的筆記或逐字稿片段。
- 把程式碼或設定片段整合成單一參考檔。
使用步驟
- 依應出現的順序選擇文字檔。
- 設定分隔標籤。
- 執行合併。
- 下載合併後的 TXT。
精確度、限制與實務建議
- 可以的話請把檔名放進分隔標籤——檔案一旦串接，最先消失的就是來源資訊。
- 選取順序決定合併順序，順序嚴格時請先為檔名加上數字前綴。
- 各檔案編碼應一致。UTF-8 與舊編碼混用，合併結果會出現亂碼。
- 請合併副本而不是原始檔。一旦串在一起，要再拆回各來源檔就是沒人想做的手工活。
常見問題
可以合併 CSV 嗎？
它是串接文字，每個檔案的標題列都會重複出現。表格資料請改用 CSV 合併工具。
有檔案大小限制嗎？
實際限制在記憶體。超大量的日誌建議用命令列工具合併。
可以合併不同類型的檔案嗎？
任何純文字都可以。二進位檔不是文字，合併結果無法使用。
換行符會統一嗎？
檔案是原樣接合的，因此 Windows 與 Unix 換行混用的情況會一併帶進合併結果。
