Question: I am trying to restrict typing more than 4 decimal digits in textbox, Can anybody help me on this please?

```
<input type="text" class="txt" id="txtValue"  ng-model="serviceParam.Value">

```

important thing is, validation should happen when typing and not focus-out(tab out).

Answer: 
If you know the specific rows you are interested in, you can skip from the top using `skiprow` and then parse only the row (or rows) you want using `nrows` - see [pandas.read\_excel](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.read_excel.html)

```
df = pd.read_excel('myfile.xlsx', 'Sheet1', skiprows=2, nrows=3,)

```
You could use `pd.read_excel('C:\Users\MyFolder\MyFile.xlsx', sheet_name='Sheet1')` as it ignores empty excel cells.

Your DataFrame should then look like this:

```
    A      B     C
0   Start NaN   NaN
1   3      2     4
2   7      8     4
3   11     2     17

```

Then drop the first row by using

```
df.drop([0])

```

to get

```
    A      B     C
0   3      2     4
1   7      8     4
2   11     2     17

```
