Trying to remove all commas from a single line of text SharePoint Online field entries.

Any ideas on how to achieve that, any formatting formulas, or JSON?

Thank you in advance!

  • Where are you trying this? What have you tried so far? What worked, what did not work? Please be a bit more specific.

  • Hi Nils, tried this formula that is meant to be for a single line of text, but didn't work, the commas are still present - =ISNUMBER([ColumnName]+0) . Trying to find any JSON options, but nothing so far. I guess I can do it with jQuery, but then I need to return to classic mode and I want it to work in modern. May 28, 2019 at 13:11
  • Wouldn't an SPFx extension esp. a Field Customizer be what you'd want?

SharePoint JSON formatting now supports replaceAll operator which you can use to remove all commas from a single line of text.


    "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
    "elmType": "div",
    "txtContent":"=replaceAll(@currentField, ',', '')"

Reference: SharePoint: Replace All Occurrences of Substring in a String using JSON Formatting


You would need to create an SPFx FieldCustomizer

Essentially you then would write

public onRenderCell(event: IFieldCustomizerCellEventParameters): void {
  event.domElement.innerHTML = `<div>${event.fieldValue.replace(/[,\.]/g, "")}</div>`;

or whatever modifications you'd want to make.


Json column formmatting not provide operators to remove/replace special character currently: enter image description here

A workaround is to update the single line text field with CSOM Console Application directly to remove commas, please see the same question in the Technet I have replied yesterday:
