# Interpolate or resample while exporting data
\*Resampling is a Licensed feature, get in touch with our technical support team for more details.
Select 'Batch Processing' from the Analysis window.
1. In the 'Export data' window, click the 'General' tab
* Enable 'Convert files.'
* Select the desired format for conversion, e.g., CSV
* Enable 'Convert each input file to separate output file.'
2. In the 'Input files' tab
* Click on the ‘Add file(s) for conversion’ icon
* Select the desired IVD file
* Click 'Open'
3. In the Converting Files tab
* Enable 'Change each item sampling rate using.'
* **Interpolation**: a mathematical method to calculate value at a specific time stamp, which lays on the line connecting previous and next samples.
* **Resampling**: specifies using the last known value, i.e., the value of the channel does not change until the next sample occurs.
* Enable other check boxes as desired.
* Used fix rate when processing samples at (time in msec)
* Align the beginning of the file time range by creating additional samples from 0ms
* Align the ending of the file time range by creating additional samples after the last ones.
Or
* Combine sampling rates from all items
***\*Resampling is a Licensed feature, get in touch with our*** [***technical support team***](https://www.influxtechnology.com/supportcontact) ***for more details**.*

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.influxtechnology.com/support_guides/dialog-user-guide/quick-start-guide/interpolate-or-resample-while-exporting-data.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
