I'm looking for a HTML form for mass data entry. Something where the user can copy and paste a column of data from Excel directly into the form. The data will then be used in JavaScript as an array and eventually used as an x axis on a scatter plot.
So far I've just used standard numerical data entry forms. However, this forces the user to enter the data one value at a time. The user will be dealing with potentially tens of thousands of data points, so this is obviously far too time consuming.
<form id = "xColumnInput">
<input type = "number" name = "" id = "xColumn">
<br>
<input type = "number" name = "" id = "xColumn">
<br>
<input type = "number" name = "" id = "xColumn">
<br>
<input type = "number" name = "" id = "xColumn">
<br>
</form>
