[SOLVED] Google Sheets IMPORTDATA for xlsx files

Google Sheets IMPORTDATA for xlsx files

I need to import some data that is stored online in xlsx file to my google spreadsheet.

I have no problem using IMPORTDATA for csv files, but xlsx files are not supported. Sheet is filled with weird symbols, and my guess is that it is because xlsx file is a zip archive of some sorts.

I would like to have an apps script that will create new custom function "IMPORTXLSX" with "url" parameter which I could use the same way I use importdata.

The problem is - for this I have to add SheetJS library, but I cannot find instruction on how to do that.

My knowledge on the topic is slim to none so if someone could provide script and instruction on how to add the library I would really appreciate that.

Thank you

I have tried finding scipts that and manuals that might help me, but failed

Solution

I believe your goal is as follows.

You want to directly retrieve the values from XLSX data from the direct link of the XLSX file.
You want to achieve this as IMPORTXLSX of a custom function using the SheetJS library.

In this case, how about the following sample script?

Usage:

1. Install SheetJS library.

Please copy the script of the SheetJS library from https://cdn.sheetjs.com/xlsx-latest/package/dist/xlsx.full.min.js, and paste the script to the script editor of Google Spreadsheet, and save the script.

In this case, I would like to recommend the following flow.

Add a new script to the script editor. For example, the filename is SheetJS.
Copy and paste the script of https://cdn.sheetjs.com/xlsx-latest/package/dist/xlsx.full.min.js to the added script file, and save the script.
Copy and paste the following sample script of the custom function to the other script file (It's the default script file (Code.gs)).

2. Prepare custom function.

Please copy and paste the following script to the script editor of Google Spreadsheet (this is the same Spreadsheet installed SheetJS library.) and save the script. And, please reopen Google Spreadsheet.

/**
 * Retrieve values from XLSX data of the direct link of the XLSX file.
 * @param {string} url Direct link of XLSX file.
 * @param {string} sheetName Sheet name.
 * @param {string} range Range as A1Notation except for sheet name.
 * @return {Array} Retrieved values.
 * @customfunction
*/
function IMPORTXLSX(url, sheetName, range) {
  const res = UrlFetchApp.fetch(url, { muteHttpExceptions: true });
  if (res.getResponseCode() != 200) {
    throw new Error("XLSX file cannot be obtained. Please confirm the link again.");
  }
  const book = XLSX.read(new Uint8Array(res.getContent()), { type: "array" });
  const worksheet = book.Sheets[sheetName];
  if (!range) {
    const csv = XLSX.utils.sheet_to_csv(worksheet);
    const values = Utilities.parseCsv(csv);
    return values;
  }
  var rng = XLSX.utils.decode_range(range);
  const values = [];
  for (let row = rng.s.r; row <= rng.e.r; row++) {
    const temp = [];
    for (let col = rng.s.c; col <= rng.e.c; col++) {
      const v = XLSX.utils.encode_cell({ r: row, c: col });
      temp.push(worksheet[v] ? worksheet[v].v : null);
    }
    values.push(temp);
  }
  return values;
}

3. Testing.

When you use this script, please put the following custom function into a cell. In this script, the arguments of 1st to 3rd are the direct link of the XLSX file, the sheet name, and the range of A1Notation except for the sheet name, respectively. When the range is not used, all values of the sheet are returned.

=IMPORTXLSX("###Direct link of XLSX file###", "Sheet1")

=IMPORTXLSX("###Direct link of XLSX file###","Sheet1","B2:E5")

Note:

In this script, if you don't want to copy and paste the SheetJS library to the script editor, you can also install it with the following script. But, in this case, the process cost becomes high. Please be careful about this.
```
const cdnjs = "https://cdn.sheetjs.com/xlsx-latest/package/dist/xlsx.full.min.js";
eval(UrlFetchApp.fetch(cdnjs).getContentText());
```
