XLSX (Excel) and VCF converter web version update record
August 15, 2024
1. In July, the CDN service was swiped away by nearly 100 yuan of traffic. The CDN traffic delivery strategy was changed to block download traffic from different browsers and download traffic without header access.
2. The CDN traffic delivery strategy was changed, resulting in some users being unable to download template files. A network disk download link was added.
3. I saw a similar tool website. After a closer look, hey, the template was still modified using the template of this site! It’s okay, there is no tutorial on that website, hey
4. I forgot what needs to be updated. It seems that that thing has not been updated~~
Oh, I remembered again that the website registration query URL has changed, and this site will also be updated synchronously.
Ahem, let me promote this website. This website supports free export of address book to Excel, VCF version conversion (conversion between vCard 3.0 and 2.1), and also supports export of VCF (vCard), Excel, CSV, and TXT to address book format.

1. I saw on the 52pojie website that the free CDN service provided by bootcdn was poisoned, which would cause their ads to pop up inexplicably on the website (not this site's ads, and cannot support the operation of this site).
This update replaces bootcdn with the CDN service provided by ByteDance.
2. Remove invalid ads.

1. Our server encountered a large number of DDos attacks on May 9, 2024, and Tencent Cloud continuously blocked our IP address (IPv4)!
If you encounter a 400 error, please switch to IPv6 and try! .
During the solution of this problem, I tried to hang Cloudflare and use my vps in Hong Kong. Cloudflare cannot provide services when it cannot return to the source. If there is only IPv6, the certificate and jump problems cannot be solved.
In the end, I had to buy Tencent's 99 yuan/year lightweight cloud server. The lightweight cloud provides IPv4 services, and the original server provides IPv6 services.
So far, the problem has been solved.
2. Add a prompt that the homepage cannot provide services.
This website supports uploading Excel tables to convert to vCard 3.0 format files, and provides download links and QR codes for easy downloading on computers and mobile phones.
After several updates, this site also supports conversion between vCard 3.0 and vCard 2.1 versions, vCard 3.0 to Excel, csv to vCard 3.0, txt to vCard 3.0 and other functions.
The website is free to use, and the main support for the operation of the website is the advertisements on the web page.
The website limits the size of Excel files to 512KB for free.
There is also a batch conversion version,
which can be divided into vcf files according to the required quantity, such as saving 1 vcf file with 20 rows of numbers.

XLSX (Excel) File
XLSX is well-known format for Microsoft Excel documents that was introduced by Microsoft with the release of Microsoft Office 2007. Based on structure organized according to the Open Packaging Conventions as outlined in Part 2 of the OOXML standard ECMA-376, the new format is a zip package that contains a number of XML files. The underlying structure and files can be examined by simply unzipping the .xlsx file.
VCF File
The Variant Call Format (VCF) specifies the format of a text file used in bioinformatics for storing gene sequence variations. The format has been developed with the advent of large-scale genotyping and DNA sequencing projects, such as the 1000 Genomes Project. Existing formats for genetic data such as General feature format (GFF) stored all of the genetic data, much of which is redundant because it will be shared across the genomes. By using the variant call format only the variations need to be stored along with a reference genome.
