Custom number format with leading letters and numbers

[Sarah82]

Hi,

I'm tying to create a SharePoint Online List as an incident register. I'm want to have an Incident ID column formatted to display the number like such: INC001, INC002 INC003 and so on.

I can format the number column to have the leading INC but it drops off the leading 0s. I googled some code to format the number with the leading 0s but then it drops off the INC.

"{

"$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",

"elmType": "div",

"txtContent": "=padStart(toString(@currentField),3,'0')"

}"

How do I change the code so I can have the leading lettering (INC) and leading 0s so my number column displayed as previously described.

Thanks in advance

@Sarah82 you're nearly there, use this:

{

"$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",

"elmType": "div",

"txtContent": "='INC'+padStart(toString(@currentField),3,'0')"

}

@Sarah82,

Adding to answer by @Rob_Elliott:

If you have some rows with no value in this number column, above JSON will return value like INC000 for all rows: 

So instead of it, use this JSON: 

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
  "elmType": "div",
  "txtContent": "=if(@currentField, 'INC'+padStart(toString(@currentField),3,'0'), '')"
}

Output:
