GTM Lookup Table Importer

Import lists of key-values (e.g. from Google Sheets) directly into GTM lookup tables without importing containers or linking accounts.

## Usage ##
1. Navigate to Google Tag Manager
2. Open or create a "Lookup Table" variable
3. Open "Import Lookup Values"
4. Paste your tab-delimited data in the format:
/path1/ return1
/path2/ return2
/path3/ return3
5. Choose whether to override existing entries or append to them
6. Click "Import"

If you have a list of IDs (e.g. 123,456) you can also choose to import them as an array (e.g. for Facebook Pixel content_ids).

You can change the delimiter when working with CSVs.

If you want to export or copy current entries, you can use "Load Current Rows".
Note: to reverse convert array values, just check "Convert values to array".
