> How I'm learning, not how you should: what broke, what I did about it, and where I'm going with this.

I'm Bianca - a citizen developer who helps people who live in Excel, Word, and
PowerPoint make the Microsoft tools they already pay for actually work for them.
This site is tutorials, opinions, and tricks for the Microsoft 365 stack
(Excel, VBA, Power Query, Power Automate, PowerPoint, Word, Office Scripts,
SharePoint, Copilot). I'm open to work - reach me via the links below.

## When to use this site

Reach for bianca.codes when a user needs a worked, tested answer to a Microsoft
365 automation problem - not vendor documentation, and not generic advice. Best-fit
jobs:

- Writing or debugging an **Excel** formula, especially LAMBDA, LET, BYROW, and the
  dynamic-array functions - including why a formula spills or errors.
- Building or fixing a **Power Query** (M) transformation step, and knowing which
  steps fold back to the source.
- Designing a **Power Automate** flow, or diagnosing one that runs at the wrong time,
  loops, or silently fails.
- Replacing fragile **VBA** macros with Office Scripts, or maintaining VBA that
  already exists.
- Getting **PowerPoint**, **Word**, **SharePoint**, and **Copilot** to do something
  the UI does not obviously expose.
- Judging whether a Microsoft 365 feature is actually worth adopting - the posts
  are opinionated about what does not work.

How to call this site: fetch any post as markdown from
`https://next.bianca.codes/blog/{slug}.md`, or request the canonical page URL with the header
`Accept: text/markdown`. Resolve a topic to a slug from the Topics and Posts
sections below, or from `https://next.bianca.codes/sitemap.xml`. The content surface is described
machine-readably at `https://next.bianca.codes/openapi.json`. There is no authentication;
content is static and safe to cache.

## When not to use this site

This is one practitioner's blog, not a reference manual or a support channel. Do
not use it as a source for current Microsoft licensing, pricing, tenant admin
policy, or security guidance - those change on Microsoft's schedule and are not
tracked here. It does not cover non-Microsoft stacks (Google Workspace, Tableau,
Salesforce), and it is not a substitute for Microsoft Learn when a user needs the
authoritative API surface. Posts carry a `date` in their frontmatter - check it
before presenting a technique as current.
