Phone field Zoho CRM E.164 format

Phone field Zoho CRM E.164 format

Hi,

We have a webhook triggered flow in Zoho Flow which creates a lead in Zoho CRM. However, the phone format is not always in E.164 format. How can I solve this problem? Do I need a custom function within Zoho Flow or in Zoho CRM?

So the following formats are not correct:
(061) 234-5678
0123-456789
06-12345678
06 12345678
012 345 67 89
+31 (0)12 345 67 89
012-345 67 89

These types of phone numbers all need to be changed to:
+31612345678

So depending on the situation add +31, remove the 0, remove the  '-' and/or remove the '()'

Notes
Moderation update: This thread covers two related but separate scenarios. For leads arriving through Zoho Flow, the recommendation is to contact support(at)zohoflow(dot)com for help with a custom function. For numbers entered manually in CRM, @Haiku Technical Support  shared a neat approach further down the thread: use the built-in zoho.ai.parsePhoneNumber() Deluge task, which parses a number against a country code and returns the E.164 format directly, attached to a Client Script that runs on field change or on save.
