What This Page Covers
This page walks through exporting M365 Copilot conversations to XLSX specifically: when to reach for this format instead of another one, the exact steps involved, and what it looks like once you have it. Further down, you will also find every other platform Be Mimos captures and every other format you can export to, so you are not locked into a single combination once you start saving conversations.
XLSX decision guide
When XLSX is the right export format
XLSX (Excel) is CSV's richer sibling — useful when the same structured, row-based conversation data needs real spreadsheet features like multiple sheets, column formatting, or formulas, not just raw values.
This page focuses on XLSX for M365 Copilot specifically, so the decision guide below is about when to reach for this format rather than a different one — not whether M365 Copilot itself is worth saving conversations from.
Use case 1Building a formatted, presentation-ready spreadsheet of conversation data for a team or client
Use case 2Organizing many saved conversations across multiple sheets (by provider, date, or project)
Use case 3Applying spreadsheet formulas, conditional formatting, or filters directly to exported data
Use case 4Sharing structured conversation data with people who expect a native Excel file, not a raw CSV
What to check before you export
- Choose XLSX over CSV when you want native spreadsheet formatting, multiple sheets, or plan to keep editing the file in Excel or Google Sheets.
- Choose CSV instead when the destination is a script, database, or any tool that just wants raw rows without spreadsheet-specific formatting.
- Review column widths and cell formatting after opening, since some formatting choices are template defaults rather than content-derived.
How the export workflow works
This page is generated from the product fact registry, so it stays tied to supported providers, supported formats, and privacy guardrails.
- Install Be Mimos and open M365 Copilot. The extension attaches to the page automatically — there is no separate account to create before capture starts.
- Let the extension save the conversation while you work, or save the chat manually if you prefer to trigger it yourself. Either way, the saved copy lives locally on your device.
- Open your saved history, choose the conversation, and select XLSX export. The export runs against the saved copy, so the original M365 Copilot tab does not need to stay open.
- Choose XLSX over CSV when you want native spreadsheet formatting, multiple sheets, or plan to keep editing the file in Excel or Google Sheets. Keep the saved conversation in your history so you can re-export it in a different format later without redoing the work.
Why use Be Mimos for XLSX export?
The goal is not just to download a file once. It is to keep a searchable, reusable memory layer for your AI work, where XLSX export is one output option among several rather than the only way to get value from a saved conversation.
Local-first archive
Chat content stays local-first and is not uploaded to Be Mimos servers. That means the export step is just reformatting a copy you already have, not a new upload to a third-party service.
Search before export
Find the saved conversation from your AI history before choosing XLSX -- useful here for building a formatted, presentation-ready spreadsheet of conversation data for a team or client -- instead of scrolling back through the original chat to locate it.
Optional PII redaction
A Redact toggle can apply PII redaction tags across selected export formats. Review the redacted output before sharing it externally, the same way you would review any exported document.
Once a conversation is saved, switching from XLSX to a different export format later does not require redoing any of the original work — the saved copy stays in your history and can be re-exported on demand.

Every Other Way You Can Export the Same Conversation
A saved conversation is not locked to one export format. Here is what each of the other supported formats is actually good for.
Markdown
Markdown is the practical choice when the conversation needs to remain readable as plain text while preserving headings, lists, links, and code-friendly structure.
PDF is the strongest fit for a stable reading copy that can be shared, printed, attached to a record, or reviewed without requiring the recipient to edit the conversation.
DOCX
Word or DOCX is useful when the conversation is only the starting point and the next step is editing, commenting, rewriting, or combining the answer with an existing document.
HTML
HTML is useful when the exported conversation should be opened in a browser, inspected as a web document, or used as the starting point for a private knowledge page.
JSON
JSON is the format to consider when the conversation must be handled as structured data for scripts, analysis, backup inspection, migration, or a custom processing workflow.
CSV
CSV is the right choice when the value of a conversation is in its structured, row-by-row data — not its prose — and the destination is a spreadsheet or a data pipeline rather than a document.
ZIP
ZIP export is the practical choice when you need to move more than one conversation, or a conversation plus its attachments, in a single download instead of exporting each item individually.
Image
Image export turns a conversation (or a specific answer) into a visual snapshot — the right choice when the goal is sharing something to look at, not a file to edit or reprocess.
Google Docs
Exporting to Google Docs is the right move when the next step is collaborative editing, commenting, or sharing inside Google Workspace, rather than working from a local file.
Plain Text
Plain text strips everything down to the words themselves — the most universal, dependency-free format for when you just need the content, with no formatting, markup, or file-type compatibility concerns.
ShareGPT
ShareGPT format is a structured conversation-turn export built for fine-tuning or evaluating conversational AI models — not for reading, but for feeding into a training or evaluation pipeline.
Alpaca
Alpaca format restructures a conversation into instruction/input/output triples — the standard shape used for instruction-tuning AI models, not for casual reading.
Tavern
Tavern format packages a conversation as a character-card-style chat log, built for AI roleplay and companion-chat applications rather than general document use.
Ooba
Ooba format targets Oobabooga's text-generation-webui — useful when you're running or fine-tuning models locally and want a saved conversation available as chat history inside that specific tool.
