こんにちは。

現在、Windows 10上でStudioX 2024.10.14 LTSを使用して開発を行っています。

ループ内でWrite Cell Xアクティビティを使用し、Webスクレイピングの結果をExcelの5行目から下方向に繰り返し出力するワークフローをデバッグしています。
192行目でメモリ不足発生でワークフローが止まりました。複数回実行しましたが、大体192行目あたりでワークフロー不安定になり、再現しています。

このバージョンのStudioXでは、Excel処理でメモリリークが発生すると推測しますが正しいでしょうか？

Hi UiPath Corp,

I’m currently using StudioX 2024.10.14 LTS on Windows 10.

I have a workflow that uses the Write Cell X activity inside a loop to write web scraping results into Excel, starting from row 5.

While debugging, the workflow stops around row 192 due to an out of memory issue. I’ve tested this multiple times, and it consistently becomes unstable around row 192.

I suspect there might be a memory leak related to Excel function in this specific version of StudioX. Would this be correct? Any insights would be appreciated.

hi @gorby , is it possible to share the Excel activities package version as well? And is there an error message when the execution stops?

Hi @gorby

It would be great if we can reproduce it. To get there, we would need you to provide a bit of information:

  • as already mentioned by Raluca, the version of the Excel activity package is an absolute minimum
  • what would also help is a dummy, mocked-up, fresh Studio project that we could have a look at (including the dummy, sample mockup of the Excel file)

Hi UiPath Corp,

I’m busy, so I’ll need some time to create the mock. For now, I’ll submit the package version first.

Here you are. This is a dummy mocked-up. Pls download this by Jully 20 2026 JST.
After that I remove this.
