Contact lists are uploaded to the cloud account. it needs to be downloaded manually day by day and then multiple excel sheets need to be merged.2 years and four months of entry so 1000 excel sheets to download, considering around 10sec to 15-sec max per download should take around 3-4 hours of time. it is more of manual work, no special computer skills required. if you can handle excel then you will be able to do this.
