## What is File Upload in Mo?

**File upload in Mo** is a feature that lets you drop a file directly into your Mo conversation so Mo can interpret and apply its contents to your planning session. Instead of manually formatting or re-entering data, you share the file and Mo handles the heavy lifting — cleaning, mapping, and putting your data to work right away.

This is especially useful when you need to factor in information Mo doesn't have from your integrations, such as an upcoming campaign, a custom forecast adjustment, or an external supplier schedule.

### When to Upload a File to Mo:

* **Campaign planning** — Share a promotional calendar or marketing schedule so Mo can account for demand spikes
* **Forecast adjustments** — Provide external data (events, market shifts, product launches) that should influence your forecast
* **Custom inputs** — Upload a spreadsheet with manual overrides, targets, or constraints you want Mo to incorporate
* **Supplier or order data** — Share lead time changes or availability windows from a supplier outside your integrations

## Prerequisites

**Time Required:** Under 2 minutes\
**Difficulty:** Beginner

Before uploading, make sure you have:

* [ ] Access to the Mo chat in your Moselle account
* [ ] Your file ready (CSV, XLSX, or PDF formats supported)
* [ ] A clear question or task in mind for Mo to act on with the file

**Examples:**

* *"Here's our Q4 campaign calendar. Adjust my forecast to reflect these promotional periods."*

## What Mo Does With Your File

Once a file is uploaded, Mo automatically:

* **Cleans the data** — Handles inconsistent formatting, missing values, and column mismatches
* **Maps it to your plan** — Connects the file's contents to the relevant products, dates, or channels in Moselle
* **Applies it to your request** — Uses the file as context to answer your question, adjust a forecast, or flag potential issues

You do not need to reformat your file to match a specific template before uploading to Mo.

## Tips for Better Results

* **Include a date range** in your file or request so Mo can anchor the data to the right planning period
* **Label columns clearly** in your spreadsheet — Mo interprets headers to understand what each column represents
* **One topic per upload** works best — if you have a campaign file and a supplier file, upload and discuss them separately for cleaner responses

{% hint style="warning" %}
Do not upload files containing real customer names, personal information, or sensitive internal data. Use mock or anonymised data where possible.

## Frequently Asked Questions

### What file types can I upload to Mo?

**Answer:** Mo supports **CSV**, **XLSX**, and **PDF** files. For best results, use CSV or XLSX for structured data like forecasts, schedules, and order files.
