Managing contacts on an online spreadsheet is safer than managing contacts on the device. If we apply filters on the contacts and share the sheet, the list can keep growing. The sheet can be updated without showing the other contacts by applying filters on it. Sharing can be done through a public url or a web link can be posted on any website or social media site. Think about it and try it.

We talked to one of the institutes using one such product and why they switched from MS Excel to online SaaS application?
