# Data Parsing & Generation
Wire Flow data parsing and generation tasks for reading and producing XML, CSV, and Excel files within a workflow.
## File Parsing
These tasks parse a file and return structured data, or generate a file from structured data. They are typically placed immediately after a **File Upload Trigger**.
| Node | Input | Output |
| ----------------- | ------------------------------- | ------------------ |
| **XML Parser** | XML string or uploaded file | JSON object |
| **XML Generator** | JSON object | XML string |
| **CSV Parser** | Uploaded CSV file | JSON array of rows |
| **Excel Parser** | Uploaded `.xlsx` / `.xlsm` file | JSON array of rows |
Connect them in the flow and they work automatically — no additional configuration is required for basic parsing.
{% hint style="info" %}
The CSV Parser, Excel Parser, and XML Parser tasks accept the file reference object produced by the File Upload Trigger as their input. See [Triggers & Execution](/tillit/knowledge-base/setting-up-tillit/integrations/wire-flow/triggers-and-execution.md) for the expected input format.
{% endhint %}
## Storing Results for Future Use
You can use the End Event Task type to create a variable and use the results in the further nodes. Otherwise, you can only map the immediate previous results.
