### Run it

Run the server with:

<div class="termy">

```console
$ fastapi dev main.py

func xlMetaV2TrimData(buf []byte) []byte {
	metaBuf, min, maj, err := checkXL2V1(buf)
	if err != nil {
		return buf
	}
	if maj == 1 && min < 1 {
		// First version to carry data.
		return buf
	}
	// Skip header
	_, metaBuf, err = msgp.ReadBytesZC(metaBuf)
	if err != nil {
		storageLogIf(GlobalContext, err)
		return buf
	}
	// Skip CRC
	if maj > 1 || min >= 2 {
