π Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a π emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

OWASP CSV Injection apostrophe Excel save CSV reopen tab prefix guidance
π‘ Result:
OWASPβs current guidance distinguishes two mitigations:
- **Apostrophe prefix:** Quoting every field and prepending an apostrophe can make spreadsheet cells read as text, but OWASP warns this is **not reliable in Excel after saving and reopening**: Excel may remove quotes or escaping, potentially making a formula active again. ([github.com](https://github.com/OWASP/www-community/blob/master/pages/attacks/CSV_Injection.md?utm_source=openai))
- **Excel-oriented CSV:** For cells beginning with `=`, `+`, `-`, or `@`, OWASP recommends prefixing a tab **inside the quoted field**βfor example, `"\t=1+2"`. The tab remains part of the underlying data and may affect later programmatic imports. ([github.com](https://github.com/OWASP/www-community/blob/master/pages/attacks/CSV_Injection.md?utm_source=openai))
This tab-prefix behavior is based on observations in Microsoft Excel and may differ in other spreadsheet apps; OWASP says there is no universal sanitization strategy for every spreadsheet and downstream workflow. ([github.com](https://github.com/OWASP/www-community/blob/master/pages/attacks/CSV_Injection.md?utm_source=openai))
